StayStack — Hotel Offer Stacker

Find hotel room-rate offers across dates in your signed-in browser session.

StayStack turns a signed-in ALL Accor hotel search into a date-by-date offer scanner. It opens available hotels, reads their room-level named rate plans, and shows the results in a calendar so you can compare stay dates without manually opening every room. Features • Scan every check-in date in a chosen window • Filter the scan by Accor hotel brand • Inspect named Stay 3 Pay 2 / third-night-free rate plans • Optionally require a StayPlus-eligible rate while your benefit is active • Search Suite Night Upgrade-eligible stays • Run Red Hot Room in its own StayPlus-off search, clearly separate from stacks • See hotel, room, rate-plan, offer-code evidence, progress, partial results, and resume controls StayStack runs locally in your browser using your own signed-in Accor session. It does not ask for your password, make bookings, send data to StayStack servers, or guarantee availability, prices, eligibility, or savings. UNOFFICIAL — StayStack is not affiliated with, endorsed by, or sponsored by Accor SA or ALL Accor. Confirm every offer and price on Accor before booking. ``` Avoid broad city/brand keyword lists or promising “pay 1 for 3” as a guaranteed outcome. Listings must accurately describe the current product.
