Call (850) 234-5271 to contact Gulf World Marine Park (see Resources for link). This is the only way to setup a reservation with Panama City's most popular "swimming with the dolphins" experience. This is a very popular attraction so be prepared for possible long hold times when calling.
Have your credit or debit card handy, payment is due at the time the reservation is set. Include in any reservations you make information on any special accommodations you may need; for example guests without the ability to swim will need a life vest.
Try a wild dolphin encounter if all of the programs that allows for swimming with dolphins is booked. Go online and fill out a reservation form on one of the many dolphin tour site that are based locally in Panama City. Sites like Blue Dolphin Tour (see Resources) offers a one step reservation form. A representative will contact you soon to discuss a method of payment and to give you any special instructions for your tour; this site only allows patrons the opportunity to view dolphins from a boat.
