I love Costa Rica. When you're in the mountains there's nowhere to buy a fan or go to AA, that's for sure. I'm glad you're moving rooms. Are you able to sleep for a few hours during the day while your husband and daughter are out? I am sorry you're going through this. It sucks when what's supposed to be a relaxing vacation turns into a stressful situation!
Hang in there and try to have fun. xo
