I chose this cruise for two reasons: First, I wanted to go to Havana and that was an awesome experience.
Second, I wanted this experience to be reflective of how cruises used to be without all the frills and extras (these things are wonderful but I wanted to keep this cruise in line with cruising from years ago. I felt this would parallel my visit to Havana.
If you really look, there are activities and fun because it is there; it is not the Flow Rider, Zip Line, basketball courts, etc. which are truly amazing if that is what you are looking for. It is just good old time fun.
Small but manageable. Bathroom small. We had wonderful service from our Host. Would prefer a window or balcony, but this was fine.
Do it! You see it all and it is a fantastic tour. Rode in a 52 red ford in the afternoon. One on one tour.
Used Cavetubing.BZ -- fantastic day. We were the only ones at the Mayan ruins in the afternoon. Awesome!
