Actually the prices has gotten a lot better and they have good deals and new programs. Me and my GF went again one time it was $120 you get 2 meal vouchers, your picture taken and a prints, you get full access and tickets to the dolphin show.
Now they even have a thing where you can go scuba diving with dolphins and the beluga whales but that's a lot of money. If you get an annual pass witch is not much. you can take one visitor for free anytime and its always free on birthdays any age but has to be the day of birthday shown on driver license.
