Head to Gulf World Marine Park in Panama City Beach at your preferred time during opening hours with your all-day admission pass. If you want to catch all of the shows and presentations, you should arrive before 2pm.
Once you're inside, browse the animal exhibits and gardens at your leisure. See alligators, penguins, sea turtles, flamingos, and sharks, and catch live shows featuring tropical birds, reptiles, sea lions, and dolphins. You can also watch an underwater scuba demonstration and shark feedings.
Most visitors spend anywhere from two to five hours exploring the park.
