I see under the shore excursions listed for Cozumel a couple of different Dolphin Encounters. The Dolphin Swim and Snorkel which has you interact with the dolphins and then go snorkel and watch the trainer and dolphins perform "breathtaking behaviors". Dolphin Encounter says it does pretty much everything but the snorkel. I was wondering which one would be better overall for my fiance and I - we are in our mid-twenties. We are getting married the day before in Grand Cayman and our parents will be on the cruise as well. My mom is in her sixties and concerned about the snorkel portion being too athletically demanding. Can anyone provide some insight about this? It's one of her life dreams to swim with the dolphins and I want her to book the excursion that she'll get the most out of. Thanks all!
