SeaWorld, San Diego, California

Come get up close and personal with marine life at SeaWorld San Diego, where finned and flippered critters entertain and amaze you with incredible feats and comical performances. Discover Atlantis; say hello to Shamu; and feed dolphins, sea lions, and stingrays all in the same day.

One-day adult admission costs $59, but you can save by purchasing a SeaWorld Fun Card before June 30. For the price of a single-day ticket, the card allows you unlimited entrance into the park for the rest of 2008, with only a few blackout dates, as well as a ticket for one of the rides.
