cruiselover, I'm sorry. If I had taken the time to carefully read your post, it isn't Belize you needed info on.
Cozumel -- Chankanaab Park. Another great snorkeling location as well. Also great if you just want to enjoy the beach for the day. Music, food and beverage available here. Lounge chairs under palm trees. Showers, lockers. Very beautiful tropical plantscape. It's a short ride and a straight shot down the road from the pier. Good prices on souveniors in Cozumel, especially in their downtown area. We always purchase hammock chairs made by locals. Sterling silver, baskets, mexican blankets and pottery. We have been going to Cozumel since 1987 (our honeymoon) and it just keeps getting better and better. A'ndrea
