Isla Roatan, Honduras... The girls snorkeled for the first time (and loved it!)
Belize... cave tubing through the rainforest with the kids. Very, very cool.
Cozumel, Mexico... a private island, catamaran ride through the ocean, a day in the ocean and an open bar.
Food. Lots and lots and lots of food.
Assorted boat fun
And a ton of great family time.
