We're Moshe and Channa, and we're going on a 4 day adventure in Corcovado National Park starting approximately from the 2nd of March 2013. We choose Nito as our guide, from surcostours and until now we have exchanged over 20 emails, they're very friendly and informative, and they get high recommendations from other travelers.
We would like to bring the costs a bit down by sharing the guide with more people (2 or 3..?) as we will be traveling Costa Rica for a month. Please let me know if your planning the same around the same dates (we're still flexible). Reservation have to be made a moth ahead, so time starts ticking for us :)
looking forward to hearing from you!
