I'm trying to decide between two different places in the Arenal area. We are traveling there with our college-age son in late January. One place has air-conditioning and the other does not. I like the location of the non-AC choice, but I don't want to be sweating while we try to sleep either. If it makes any difference, my non-air conditioned choice is Arenal Oasis and is located amongst trees. The air-conditioned choice is Hotel Arenal Green. Thanks for your help!
