We were there in February. If I remember right, it was $25.00 for (1) 5x7 photo, or they will give you a price for the CD based on the # of people in your family. They do a fair amount of shots for each participant. I think we ended up paying $150.00 for the CD with approx. 85 photos between all of us. We are a family of 4 (2 adults, 2 kids).
FYI... most of the other souveniers are are your typical gift shop souveniers... t-shirts, picture framies, stuffed animals, etc...
This was honestly not my favorite excursion. IMHO it ended up being a basic photo op with a dolphin. I felt we were rushed beginning to end... your turn to pose for a pic, and onto the next...A lot of money for a photo op experience.
