I'm thinking that this spring I'll finally venture into central america, I'm just not sure which country yet. Who's had better experiences where? What offers the most activity? I'll definitely want to hit the beach while I'm out there, and visit some Mayan Ruins, as well as soak up some culture without getting involved in any drug deals gone wrong. :) Thanks for the help.

I would suggest Guatemala. If you want to dive/snorkel you can easily go to Belize (Caye Caulker) or the Bay Islands (Honduras). If you want some extra ruins, Chiapas (Mexico) is also close by. Tips in Guatemala: vistit Tikal by night, Coban (take the tour to the lakes and caves) and Lago Atitlan. Enjoy!
