No. The 3D/4D movies are free. The only thing that costs extra is Tuki's Island Play & Party Center (it is free for Aquarium members).
There is also a large jungle gym play area behind the movie theater on the 2nd floor that has an additional fee if you are not an annual member.
Other than the gift shop, movie theatre and photo booths I dont think so.
No
It also costs extra for the penguin encounter
