Thanks for the replies! Rodolfo,
I think that you will find many good options in Costa Rica. Based on my trip, the Cahuita y Puerto Viejo area comes to mind most strongly. Vegan offerings in Costa Rica were pretty limited, esp outside of the greater San Jose area but this place was pretty good: http://www.veronicasplacepv.com
The towns are fairly hectic considering their size but you can find great and quiet nature spots nearby. Veronica can probably point in the right direction.
Best wishes amigo! aspara-gus
Neat that ya recommend (I think) Veronica's Place too! Thanks for sharing your thoughts and tips. laura76,
My trip went pretty well. I also went to Manuel Antonio & agree with your assessment. Let me know if you have any questions about my trip!
