SEA LIFE Bangkok Ocean World has a KTC online-ticket saving from 1 September 2026 to 28 February 2027. Enter promo code KTCSL20 during the attraction’s online booking flow and pay with an eligible KTC credit card to reduce the dynamic-price ticket by 20 percent. The booking is tied to the selected date and time, so choose the slot only after the whole group has agreed.
The campaign is for Thai nationals and foreign residents of Thailand, with proof of residence required. A card can be used for up to four tickets per day. KTC also shows walk-up reference prices of THB 559 for an adult, reduced from THB 699, and THB 479 for a child aged two to eleven or an adult aged 65 and above, reduced from THB 599. Online dynamic prices can differ.
Book Online
Open the current SEA LIFE booking page through the campaign route, select the visitor types and a visit slot, then enter KTCSL20 before payment. Make sure the 20 percent reduction appears before authorising the KTC card. A code that is accepted at an earlier screen but missing from the final total has not delivered the benefit.
Carry Proof
Each visitor should have the identification or residence evidence required by the attraction. The offer is not framed as a general tourist discount for short-stay foreign visitors. If eligibility is uncertain, contact the attraction before buying because completed tickets are non-refundable and resident checks can occur at entry.
Fixed Plans
Tickets cannot be cancelled, refunded or rescheduled after purchase. Leave enough travel time for Siam traffic, mall navigation and queues. SEA LIFE is in the basement of Siam Paragon, reached easily from BTS Siam. A late arrival may shorten the visit even when staff can still admit the group.
Points Option
Eligible cardholders can register for an additional points cashback route of up to 13 percent under the campaign conditions. Treat that as separate from the ticket saving: register as directed, keep the confirmation and do not assume every card or transaction qualifies. The immediate 20 percent reduction should still be visible at checkout.
Family Costs
Check how the booking system defines child age on the visit date and whether children under two require a zero-price reservation. Compare timed online prices with the counter reference, but include certainty: a booked slot can be valuable on a busy weekend. Food, photographs, gifts and other add-ons remain outside the ticket saving.
At Entry
Keep the booking confirmation, payment card and resident documents accessible. Do not rely on one phone with a nearly empty battery. The attraction may change operating hours, exhibit access or special-event conditions, so verify the live opening schedule before leaving home.
