Singapore Oceanarium turned one on 24 July — it opened to the public on 24 July 2025, three times the size of the S.E.A. Aquarium it replaced, across 22 zones. The anniversary offer sitting on its own ticketing page is the cheapest way a local group of three is getting in this year: SG Residents Exclusive: Buy 2 Get 1 FREE, listed from S$110.00.
> Quick view: 2 one-day tickets + 1 free one-day ticket, from S$110 · about S$36.67 a head · purchases AND visits 8 Jul – 30 Sep 2026 · every ticket holder must be a Singapore resident, ID checked at entry · minimum 1 day advance booking · non-refundable, non-changeable.
What you get, and what it is worth
Straight off the official page, the bundle contains:
- 2 x Singapore Oceanarium One-Day Ticket
- 1 x Complimentary Singapore Oceanarium One-Day Ticket
Resorts World Sentosa lists the Oceanarium's one-day rates as Adult (13–59) from S$55, Child (4–12) from S$43 and Senior (60 and above) from S$43. So the S$110 headline is exactly two adult tickets — and the third adult walks in free.
| Three adults | Cost | Per head |
|---|---|---|
| Standard one-day tickets | S$165 | S$55.00 |
| Anniversary Buy 2 Get 1 Free | S$110 | ~S$36.67 |
| Saving | S$55 (33%) | — |
S$36.67 a head is below the child rate, which is the whole reason this is worth planning a day around rather than stumbling into.
One honest gap: the promotion page does not state whether the bundle can be built on child or senior rates, so check the ticket-type selector before you pay instead of assuming a family of three prices the same way.
The four catches
- All three of you must be Singapore residents. The terms say the offer is valid for Singapore Residents with an official Singapore Photo ID, that ID is required for entry, and — the clause that does the damage — that all ticket holders must be Singapore residents. Two locals plus a visiting friend does not qualify. ID is checked at the gate, not at checkout, so you find out late.
- Minimum 1 day advance booking. There is no same-day walk-up at this price. If you are reading this on the way to Sentosa, you are booking for tomorrow.
- Buy by 30 Sep, visit by 30 Sep. The wording is "purchases made between 8 July and 30 September 2026, for visits within the same period". Both ends sit inside the window — a ticket bought on 29 September cannot be used in October.
- It is final once confirmed. Non-transferable, non-refundable, not for sale or exchange, with no cancellations, refunds, exchanges or modifications after the order is confirmed. Tickets are dated, so a rainy morning or a sick child is your loss.
Two scheduling notes on top: the offer is not valid during Exclusive Events, and timed-entry tickets are required during peak periods — school holidays and public holidays being exactly when that bites. Pick your slot at booking.
Who this actually suits
- Three adults, weekday, September. The best-case use: the full S$55 saved, quieter halls, and the 30 September deadline lands neatly after the September school holidays.
- Two adults and a teenager. Anyone 13 and over pays the adult rate, so a teen counts as a full-price head — which makes this group the same clean win.
- Not the mixed-nationality group. If one of your three is on a tourist visa, buy standard tickets and skip the queue-side argument.
- Not the frequent visitor. More than two trips before it lapses and the 6-month Season Pass is the better maths — unlimited visits, a complimentary audio guide, a one-time Animal Spotlight: Sea Jellies programme (U.P. S$28), S$20 in welcome vouchers, priority access, 10% off a-la-carte tickets to the Oceanarium, Universal Studios Singapore and Adventure Cove Waterpark, and 10% off selected in-park F&B and retail.
Planning the visit
Singapore Oceanarium, 24 Sentosa Gateway, Sentosa Island, Singapore 098137. Weekdays 10am–7pm; weekends and public holidays 9am–9pm — the weekend day is four hours longer, which matters if you are trying to justify S$36.67 across 22 zones. Parking is at B1 East Car Park; the recommended drop-off is the B1 Casino Entrance.
Also currently on the same ticketing page if the bundle does not fit your group: Twilight Waves (4pm–8pm entry, from S$55, bundled with a S$5 retail voucher and a S$5 meal voucher, neither with a minimum spend) and Silent Disco: Deep Blue Beats (from S$55), the Oceanarium's after-dark event.
