Yes. The guides pay special attention to non-swimmers and everyone is required to wear life vests.

You are allowed to take your own photos but I suggest you also purchase the professional ones. They are really good. If you can, ask for Sosa. He’s the best guide.

Our guide took us to the Cenote Estrella. It was lovely.

Everyone has a first time snorkeling, and the guides will help you put on equipment. None of the stops is scary. I have done this trip 3-4 times over many years. Whoever picks you up will be with you the whole day. By the time you reach first stop, by chatting in the van he will know who might need help. Since there are numerous van loads daily, the stops may be in different orders. The open cenote and cave are not too strenuous. Yal-Ku lagoon is big. They will offer to keep you swimming over an hour, but you can quit earlier. Enjoy!

I agree with Sunset151. We had several people who couldn't swim. The life vests and flippers help you stay at the surface and move through the water. The guides quickly adjust to meet any participant, and offer kind, supportive encouragement. They were some of the best guides I've ever had on any trip.

Your belongings are safe in their van or in the lockers as mentioned by Sunset151. Plan on a long-sleeve rash guard to minimize your need for sunscreen. Your face will be in the water, and you really shouldn't need much on your face as a result. Biodegradable sunscreen is a must, if you feel you need it. I chose to wear a long sleeve rash guard and board shorts so I could go sun-screen free and reduce damage to fragile corals. This trip is lovely. One stop is a colder, darker cavern, and you won't see fish or things in that water. Cool, otherworldly experience, though. The cenote has a large dive spot, and then a shallower area that looks like Ireland-green but underwater. Tiny, tiny fish are all around, and delightful. The isleta (where ocean meets fresh water) has a bit more current, and you will see more variety of fish. When you first get in the water, if you are new to snorkeling, hang out near the steps so you can adjust your mask and make sure it's not leaking. Once your mask is positioned correctly, it will be amazing to see so much underwater. Enjoy!

I believe there is. I stayed there a couple years ago. Best bet is look for the Expedia shirt at the hotel and tell them you want to go snorkeling with Mayan Adventures. (Other tour booking groups may book them as well but I prefer the Expedia people for service, refunds if needed etc) As far as I know they’ll pick up at pretty much any of the resorts.

This is a half day tour, so you will either be in the morning group (as we were) or the afternoon. We were picked up at 7:10 for our morning tour, and our hotel was about 30 min from the dock. I would be that those who were picked up at 10:40 we booked on the afternoon tour, and likely their hotel was more than 30 min from the dock. We sailed around 9, and then returned around 1:45 or so.
