My wife and I along with another couple are planning our 2nd trip to Costa Rica in early 2011 since it's the place we compare all other vacations too. We were there four years ago and without a doubt it was the best vacation ever. We flew into San Jose rented a car then spent time in Arenal, Monteverde and Manuel Antonio. We could easily do the exact same trip over again but we would like to check out other areas. I know this is probably been asked way too many times to count but if we had to switch Arenal for something similar is there anything close? How about Monteverde and Manuel Antonio? I am just starting my research but thought I should post here first.
