Does anyone know where I can find these deals for this? I'm looking for information on how to buy Disney/Universal/Seaworld tickets in a group instead of separately, if possible.
Just tickets? Support the forum Ticket Sponsor can contact OFTEric, his outfit sells all the local attraction tickets and he may be able offer you a deal on a "bundle" of them. Strictly speaking the different park groups for the most part don't bundle the tickets together as each want to keep the tourists inside one of thier parks and not running off to the others.
Universal has ticket bundles for Citywalk, IOA and their studio's. Sea World is trying to directly compete now with Aquatica, Discovery Cove and Seaworld Orlando. And of course Disney has the most with 4 them parks, 2 water parks and 2 entertainment districts.
