KTC cardholders can use The Ultimate Buffet offer at participating Marriott hotels in Thailand until 31 July 2026. Lunch and dinner use a come-four-pay-three format, while breakfast gives 50 percent off the second diner when two people eat together. The offer began on 15 May and covers selected restaurants in Bangkok, Pattaya, Phuket, Koh Samui and Khao Lak rather than every Marriott venue.
The value depends on the restaurant, day and meal period. KTC publishes starting averages of THB 666 net per person for the lunch calculation and THB 819 net per person for dinner when four eligible diners share the bill. The second breakfast starts from THB 275 net. Treat those as campaign starting points, then confirm the restaurant’s current buffet price, inclusions and eligible dates when reserving.
Choose The Meal
Breakfast is simplest for two diners because the second person’s eligible buffet is reduced by half. Lunch or dinner makes most sense for a group of four, where one of four eligible buffet charges is removed. A party of three does not unlock the come-four-pay-three calculation, and a larger group should ask the restaurant how it divides qualifying sets.
Book Directly
Reserve with the participating hotel restaurant and mention the KTC Marriott promotion before giving card details. Ask whether weekends, public holidays, themed nights or premium menus are excluded. Availability and table allocation remain with each venue, so showing up with an eligible card does not guarantee a promotion table during a sold-out service.
Pay Correctly
Use an eligible KTC credit card for the qualifying bill. The cardholder should be present, and the restaurant may calculate the benefit only on full-price adult buffets. Drinks, supplements, children, service charge and items outside the buffet can follow different rules. Check the bill before paying because the saving should be applied at the restaurant rather than claimed later.
Points Option
KTC also describes a separate route for receiving 13 percent credit back in KTC FOREVER points after registering and redeeming points equal to the transaction amount. That points mechanism has its own conditions and should not be assumed to stack with the buffet price privilege. Decide whether the immediate dining offer or points route is the useful benefit for your booking.
Where It Works
The campaign page lists participating Marriott restaurants across five destinations. Open the current property list rather than relying on the Marriott name alone: brands, outlets and meal periods vary. If a trip is built around the deal, call again on the day to confirm service hours and that the promotion remains available for the chosen table.
What To Confirm
Ask for the final adult price, taxes, service charge, child policy, beverage inclusions, cancellation terms and any blackout date. For four diners, request the expected total after the promotion. That one figure makes comparison easier than concentrating on the percentage headline, especially when two buffets have very different base prices or premium supplements.
