This response is based on a PP and my knowledge of the area. IE; No swim caves on Cozumel.
This excursion takes you to the mainland of Mexico. You have to take the ferry from Cozumel to Playa.
I just want to add, once you debark the ship, you spend at least one hour traveling in another boat, each way, crammed with others, across a strait, known for unpredictable seas, to cram in a vehicle, then descend in a cold cave, with cold water, to experience dark surroundings.
Yes I have done this. But from the mainland. Many don't realize you ferry from Cozumel to the mainland. This excursion can be wonderful given daily conditions.
The ferry can be unpredictable regarding the seas.
Just trying to share. Yes obviously looking back we would have chosen a different excursion. However, we are thrilled that we did such a venture, I only question the value of any mainland excursion from Cozumel. The time involved is significant. YMMV.
