Ok - so kids are 10, 8 and 8. All athletic, active, adventurous kids. Experienced travelers, comfortable in a variety of situations, but also, kids who want to have fun. Husband and kids enjoy snorkeling. I? Do not, but I do enjoy sitting on a beach while THEY snorkel So, between the three - tell me your experience. I've heard a variety of reviews, but none seem to compare to one another. Thoughts?
