You might have come to the wrong place to get an unbiased opinion.
Discovery Cove is such a unique experience from top to bottom. The dolphin encounter is the highlight, but it is a great day even without that.
We are booked for next June...our second trip. We all (DW, DD9, DD11) did the dolphin swim last year. Next year, the DD's will do the dolphins while DW and I enjoy them enjoying their experience.
We have often commented that DC was the one real vacation day in the middle of our Orlando vacation. Impossible not to relax and feel like your in the South Pacific. Snorkel the coral reef or an awesome lazy river (not like the water park concrete troughs). Feed exotic birds in the aviary. Just read a book.
Don't forget the admission price includes valet parking, wet suit use, snorkel to keep and a great gourmet lunch. And when you're done, you've had a unique experience.
Worth it, dolphins or no dolphins?
YOU BET!!!
