We own Sea Tiger in TMM fleet. I have not stayed there, but had a client who did stay at FBH. He and his son reported that it was basic, clean and convenient.

I did not know Jason (Coconut Breeze) did 1 night rentals, but that would be nice to enjoy CGB for 1 night.

I too have enjoyed eating at The Pub recently.

If a "sleep aboard" is available, I highly recommend that as the costs likely similar to hotel and allows you to get settled aboard, provisioned and ready to go earlier the next day. TMM charters officially start at noon, but they will allow/assist you in getting off earlier.
