Great Harbour at IconSiam has a KTC points privilege from 1 September to 30 November 2026. An eligible KTC credit-card holder can redeem 999 KTC FOREVER points for THB 250 off the buffet price per person. The deal is specific to Great Harbour at IconSiam, so it should not be assumed to apply to another restaurant, branch or menu.
The published mechanic is one redemption right for one buffet and one person, with unlimited uses during the campaign while the card account and points remain eligible. Gift cards, gift vouchers and alcoholic drinks are excluded. Several specialist card products are also excluded, and the discount cannot be combined with another promotion.
Use The Offer
Reserve Great Harbour directly, mention the KTC 999-point privilege and ask which buffet sessions qualify. At the restaurant, tell staff before ordering and open the redemption route while the team can verify it. If several eligible cardholders want to redeem, ask whether the venue must split the transaction and how children or supplements will be handled before the meal begins.
Read The Conditions
The campaign runs from 1 September to 30 November 2026 at Great Harbour, IconSiam. Each 999-point redemption gives THB 250 off one qualifying buffet for one person. The saving excludes alcohol, gift cards and vouchers and cannot be combined with other promotions. KTC also lists excluded card products, so the exact card and current live terms matter.
Judge The Value
Compare the current buffet price, service period, child policy and any premium supplements with what the table will actually eat. Redeeming 999 points makes sense when Great Harbour is already the preferred meal and those points are not earmarked for a higher-value use. A cross-town journey, extra drinks and chargeable upgrades can easily outweigh the headline saving.
Plan The Purchase
IconSiam is reachable by Gold Line or river shuttle, but evening and weekend travel needs a buffer. Confirm the sitting length and last order, then arrive together because a buffet clock may start when the table is seated. Save the current promotion page on the cardholder’s phone and keep enough battery and mobile data to complete the redemption at the venue.
Before Payment
Open the live campaign page for Great Harbour on the day and ask the merchant to confirm the benefit before payment. Keep the booking or order confirmation, itemised bill and card slip until the saving has appeared. If the live checkout, code or venue team shows a different amount, pause and resolve it before paying rather than relying on an old screenshot.
