I love drift diving in Cozumel, and have heard that there is really good drift diving in the Grenadines off of a live aboard. Does anyone know about this? Is a live aboard worth the expense? When we go on vacation, we just want to dive, not really shop or anything like that. We are going to start graduate school soon, and so will be really tied up for a long time, and I want to go on another dive vaacation before we get tied down. any suggestions? No shore diving, my husband can't reallly handle that, somewhere in the Caribbean. Dove Cozumel 3 times lately, Jamaica, Calif, Sea of Cortez, been diving since 1977. Since we're going to grad school, can't really splurge
