Allure Dolphin Experience Western Caribbean - Help Please?

[WIFosterMama]

There are 13 of us going on Allure at the end of March this year for Western Caribbean: Nassau, Cozumel, Costa Maya and Roatan.  Of those 13, three kids: 7, 11 and 13 have had no dolphin encounter/swim experience.

 

Which of the above ports would you choose to do an excursion at?  I have been looking at excursions between RCCL and third party sites for each port as well and it's getting overwhelming.

 

We currently have plans for all 13 of us to do a beach break in Cozumel, but willing to change as we have no plans at other ports set in stone.

 

Thanks for any guidance!
