We want to do this in Cozumel and I requested info from the place that does the Dolphin Encounter and this was their response (I just copied and pasted it)
Thank you for contacting Dolphin Discovery.
Please advise the exact date of your cruise, so that I can check if we have any availability - our allocation for sale through the Internet department is very limited on Wednesdays, due to the volume of visitors from the various cruise ships that dock in Cozumel on that day.
If available, the regular Encounter time is at 2.30pm. The program lasts 45 minutes, (check in 30 minutes prior to program) and 45 minutes should be allowed after the program has finished, should you wish to view the photos and video that will be taken.
The program costs US$75.00 per adult, and US$70.00 per child. There is an additional charge of US$10.00 per person entrance fee to the park (children below age 7 enter free of charge).
To get to us, you would take a taxi from the dockside to the park (about 15 minutes), which would cost approximately US$10.00 each way (up to four people).
Best regards,
Marian Davies
Hope that helped Roy....
