Buying SeaLife tickets online provides a booking confirmation file with details and a barcode. You can open this file on your phone and show it to staff for entry. You can easily spend the whole day there; the atmosphere is great. Inside, there are a few small food and beverage stations, clean restrooms, and a souvenir shop with cute items at reasonable prices for a tourist attraction. Afterwards, you can proceed to Madame Tussauds, using the same barcode scanning process as for SeaLife. Inside, you'll find wax figures of various famous people, and small activities like piano, golf, soccer, basketball, and tennis, complete with costumes for role-playing. Overall, it's a good option, cheaper than buying at the counter, and you get two tickets in one.
