ok here is how the Anguilla dolphin thing went in detail...
you have to get up EARLY this part sucks as you have to be in rocken bar d at 7:30 at the latest... why does it suck????
well.... the ferry for Anguilla (which is right near the ship maybe a four min. walk) did not arrive until about 8:45, I kept thinking how much longer I could have slept... but you need to let go of that "main-lander" thinknig and go to "island time" as nothing on this excursion is in our realm of time... (often it is to your benifit though

)
you ride the ferry (a wild ride!! kinda like a flume ride) and get to the island in about a half hour or so, you board busses that are comfy enough with AC and a free Anguilla book and drive to the site. It is a cool ride - TONS of goats, there are almost three times the amount of goats on the island than people!!
Once there you are split (via your wrist bands) into two groups, group one goes to the beach, and group two gets split again into three groups, ( I would assume the same happens to group one once they come back up from the beach) group one does the dolpins first, group two does the stingrays first and group three does the birds and hermitcrabs and turtles first. Everyone rotates.
It is WAY more than an encounter with the dolphins, our group was spit again and we had three dolhins for two groups of five, you got to kiss them, dance with them, swim with them, plya ball iwth them, race them, it was really cool as one dolphin is not a year old (well he is now as his bday is 12/26- anyhow he is still nursing so you could swim down and look at mom's mammoray glands. very cool) This was by far the best excursion I have ever done, the beach is AMAZING the sand is so soft and like a foot thick, you sink in when you walk, big waves and only you and 29 other people are there, the only thing negative was the lunch and the wait to go home on the ferry-island time again. The lunch probably was good but we were buying pictures so we missed it.
