Hi ya
me and my boyfriend went to Cancun in Spetember and we swam with them at the aqurium, it was brilliant, where as from what we heard from toher people they didint get in the water straight away, you spend the full hour in the water with them swimming around you.
we did the $115 swim which is the best one. we got pics of them kissing us, holding fins and did the footpush. you have 2 dolphins with two groups so thatf our dolphins in the pol at a time. The instructors are brilliant and have a real laugh with you and the dolphins. they swim around you you can touch, they get them to talk to you and everything. After we bought the video of the whole experience for $29 which is really good and got the pics as well.
Also take an underwater camera with you, you can use them as well and we got some brilliant pics ourselves, plus here you get to go in the aqurium first and look at everything else, pluds that evening if you keep your band on you can watch the dolphin show for free.
enjoy!!!
