We did the Manta Ray night snorkel experience with Lawrence and Eric as our guides, and those two were awesome! We booked the 5:30pm trip, and my understanding is that this is the best time of day to see the most action, right at dusk. The small group experience was great, it was only my wife and me and four other guests, which made for a very personal experience. We saw a couple of other tours, presumably from a different company, that had maybe 20 or so guests packed into a boat, and it didn't look nearly as good as what we experienced. I would highly recommend this trip to everyone! Again, Lawrence and Eric were fantastic, and the small group is definitely the way to go! Thanks guys, great job!
