This is useful if you were already planning a hotel buffet rather than looking for a reason to over-order. The strongest readers are families, small groups and visitors comparing hotel lunch or dinner options, because the KTC page ties the privilege to real meal periods instead of a vague discount line.
The cleanest way to use it is to choose the restaurant first, then call the hotel and ask which Marriott Ultimate Buffet privilege applies on your date. A Come 4 Pay 3 lunch can be excellent value for four diners, while the breakfast offer makes more sense only when the second diner and hotel branch fit your plan.
What You Get
Marriott The Ultimate Buffet Promotion with KTC Credit Card runs at Participating Marriott International hotels and resorts in Thailand. The listed benefit is Breakfast: second person 50% off from THB 275 net/person for the second diner; lunch and dinner: Come 4 Pay 3 from THB 666 and THB 819 net/person respectively; optional 13% cashback with KTC FOREVER points. The campaign window is 15 May 2026 to 31 July 2026.
To use it, Book the participating restaurant, identify the KTC privilege before dining, pay with an eligible KTC card and register/redeem points where the cashback mechanic is used. The relevant locations are Participating Marriott restaurants in Bangkok, Pattaya, Phuket, Samui and Khao Lak.
Before You Book
- Confirm the participating Marriott restaurant and meal period directly with the hotel.
- Ask whether service charge, tax, drinks and special menus are included in the quoted net price.
- If using points for cashback, complete the required KTC registration or redemption flow on time.
- Avoid assuming the same terms apply in Bangkok, Phuket, Samui, Pattaya and Khao Lak.
Who It Suits
KTC lists the campaign until 31 July 2026. Treat that as the outer window, then verify restaurant availability before inviting a group.
Reader Questions
Is the Marriott Ultimate Buffet KTC deal current?
Yes. The source page checked for this package lists the campaign window as 15 May 2026 to 31 July 2026.
What is the main risk?
The main risk is assuming the headline benefit applies to every branch, date, menu or product. Confirm the participating outlet and redemption method before spending.
Should I use it for a casual purchase?
Use it only when the deal matches a purchase or booking you already want. A discount is not helpful if it sends you across Bangkok or into a higher spend than planned.
