After cruising 2 winters in the Yucatan, I gotta admit that Port Adventuras has my favorite marina.
It is modern and offers all of the comforts of home. (important if you''ve been anchoring out a lot, and have a wife on board, accustomed to occaisional pampering).
There are good restaraunts, shops and US newspapers dockside, and lots of dolphins swimming in the wet slips close by.
Cozumel is the pits concerning marinas. Neglected, expensive and now run by the government, you need a 15 ft boarding ladder
just to climb out on to the dock.
Yep, Isle Mujeres is nice as well, but if you are heading South from there, Cancun and then Port Adventuras are safe havens on your way to Belize.
Best to ya,
Traff (heading back to the Bahamas Dec 26th for "Junkanoo")
