DO NOT BOOK THROUGH TRIPADVISOR ❗️❗️❗️
Coex aquarium told us that our TripAdvisor booking was not valid as of July 2023. The Aquarium itself was an amazing experience, but we had to purchase the tickets there and submit a refund to TripAdvisor because our ticket, despite having a QRcode, was not valid.
To reiterate, the aquarium is amazing, but you should purchase the tickets there as opposed through TripAdvisor simply because the aquarium will not accept your TripAdvisor admission. You should definitely visit this aquarium if you are visiting Seoul.
Hopefully this helps you avoid spending on an extra set of tickets that you already purchased.
