*Marriott is moving a large, mixed hotel estate off FOSSE, Full Service, and Galaxy Lightspeed. The new stack is meant to connect the desk, the reservation, the loyalty number, and the P&L. Owners will score it on whether rooms still sell and check-in still moves.*

Marriott International’s Power of M is one of the larger hotel-technology conversions now running in the industry. The work covers property management, central reservations, loyalty, guest data, financial workflows, and commercial tools across a managed and franchised portfolio that was assembled over decades.

Marriott has described modernization across core property management, central reservations, and loyalty. Job postings for deployment leadership, command-center operations, network readiness, learning and development, and performance management show the program has left the planning deck and entered live hotel operations. Some regional deployment roles run into 2027.

The strategic case is easy to state. A connected guest-data environment can support more consistent recognition. A modern platform can accept new tools without a rebuild for every change. Better integration can cut manual handoffs among reservations, operations, loyalty, finance, and sales. Standardized workflows can raise consistency across brands and ownership structures. A cleaner data layer can support automation, targeted marketing, and later AI work.

The execution risk sits in the same sentence. Hotels still have to take reservations, assign rooms, collect payment, protect rates, recognize loyalty members, and close the books every day while the conversion is underway.

**What happened**

Power of M is Marriott’s operating-platform rebuild. The property-management system is the piece hotel teams will see first. The larger design is a cloud-based environment that ties arrivals, departures, inventory, guest requests, rates, payments, service recovery, and reporting to the systems above the hotel.

Large hotel companies carry technology that was built for an earlier operating model and then stretched across acquisitions, brand standards, regional practices, and mixed ownership. Those systems can still handle a basic check-in. They also slow integrations, split guest records, add manual work for associates, and force hotels onto workarounds that are hard to train.

Marriott has put real money behind the change. The company is committing $1.1 billion in investment spending during 2026, with more than one-third directed toward digital and technology transformation. Power of M sits inside that budget.

Marriott already has scale, a large loyalty program, and substantial distribution. Power of M is the attempt to make that scale cheaper and faster to operate.

The clearest sign the program is live is the deployment machinery around it. Marriott postings describe run-of-show leadership, master timelines, command-center coordination, pre-go-live readiness, cross-functional escalation, and post-deployment reviews. One role owns risk management and operational lessons from each wave.

That staffing pattern is the story. Marriott is converting operating environments that cannot pause. A miss on room assignment, payment processing, inventory, or rate configuration does not stay at the front desk. It moves into the call center, the revenue office, online availability, labor productivity, guest scores, and owner confidence.

Marriott is hiring against those failure points: readiness, technical support, learning and development, network readiness, finance transformation, and revenue management. The timeline is multi-year.

**Why it matters**

A PMS swap is a hotel event. Power of M is a company event that happens inside hotels.

Reservations agents, revenue managers, controllers, general managers, and loyalty members all touch the same guest record. If that record is cleaner and shared, recognition at the desk gets easier and commercial decisions get faster. If the conversion is rough, the same people absorb the friction at the same time.

At Marriott’s U.S. and Canada Select Brands General Managers Conference, Power of M was introduced to nearly 5,000 general managers. The pitch described a cloud-based front-office environment, associate feedback during development, and more time for guest work once teams stop navigating older systems.

That is the upside case Marriott is selling to operators.

Frontline commentary is more mixed. Associates who expect a transition, or who have just completed one, talk about long training, complicated cutovers, early operational frustration, and the pressure of learning new screens while a guest is waiting. Large conversions often produce that reaction in the first waves. In a hotel, the tolerance for it is thin. A system that slows check-in, complicates payment, makes inventory less reliable, or sends an associate through extra screens during a 3:00 p.m. arrival rush will be judged immediately.

The useful reading of that feedback is a demand for a better implementation. Associates will accept a new system that works at the desk. They will not accept a conversion that makes a waiting guest wait longer.

Training is the variable most likely to decide the local result. Software can be competent and still fail a hotel if associates do not know the new workflows, if managers cannot coach in the first week, or if support disappears after go-live. Public comments describe months of planning at some properties and heavy training loads at others. Marriott’s own hiring in learning and development, regional adoption, property readiness, and pre-go-live validation matches that risk.

One Marriott hotel team that completed a Power of M transition in June 2026 described months of planning, training, communication, and a deliberate effort to protect the guest experience through the change. Teams that report a cleaner landing tend to describe that same pattern: protected training time, configuration that matches how the hotel actually runs, support during arrivals, departures, and night audit, clear escalation for reservation, inventory, payment, and reporting issues, simple job aids, and leadership that treats the first weeks as a stabilization period.

Revenue protection is the other test. Marriott has posted a Power of M performance-management role focused on identifying and resolving pre- and post-cutover revenue risk. That hire is an admission that a conversion can cost money. Rate plans configured incorrectly, rooms that drop out of sale, reservation data that breaks, overbooking tools that staff cannot use, delayed financial reporting, or a revenue team that no longer trusts the numbers will show up on the owner statement. Short instability is expensive in a high-demand market or a compressed event week.

The conversion count will be a program metric. The owner metric is whether the hotel performs better after the learning curve.

**What hotel leaders should do next**

Ask for the local run of show. A GM and an asset manager need the cutover date, the support window covering peak arrival and audit, the escalation path for inventory and payment, and the person who owns rate and availability integrity in the first 14 days. The corporate slide will not name those people.

Protect training hours on the schedule. A conversion that is staffed as extra work on top of a full occupancy week will train in front of the guest. Build the hours before go-live and keep a coach on the desk through the first weekend.

Test configuration against how the hotel sells. Group blocks, negotiated rates, packages, house use, and walk policies are where conversions usually break. Walk those cases in a practice environment before the live night audit.

Put a revenue watch on the two weeks after cutover. Compare rooms available to sell, pickup, ADR, and denial or restriction activity against the prior four weeks and against the forecast that was built on the old system. If the numbers move, assume a configuration or interface issue until proven otherwise.

Separate associate sentiment from system defects. Frustration with new screens is expected. Missing payments, wrong inventory, or a loyalty profile that fails to appear at check-in is a defect. Those need different owners and different clocks.

Owners and franchisees should ask how performance will be measured after stabilization: check-in time, manual workarounds retired, reporting hours recovered, integration reliability among reservations, loyalty, and the property, and the hotel’s ability to manage rate, inventory, ancillary revenue, and service recovery. If those measures are absent, the program is still being scored as an IT install.

**What this comes down to**

Power of M will be judged at 7:00 a.m. on a heavy departure morning, at 3:00 p.m. when the lobby fills, and late at night when a small team is running audit and handling the guest who cannot wait until morning.

Marriott has funded the platform, staffed the rollout, and taken the idea to thousands of general managers. The remaining work is operational: disciplined waves, training that actually happens, fast repair when a rate or a room file breaks, and proof to owners and associates that the new day is easier than the old one.

If those pieces hold, Marriott gets a common operating layer under a loyalty program and a distribution system that already have scale. If they slip, the cost will show up as slower desks, nervous revenue teams, and owners who remember the conversion longer than they remember the strategy.
