Yes GCG is great as well, but it costs a lot to get to Brazil and takes a long time to clear customs here. Chanca Piedra has been unbeliavable.
Florianopolis is where I spend my summer vacation. If you ever come down again let me know. We can have some caipirinha together. I usually go to the south of the island where it is still quiet and with fewer people.
Um abraço
