My boyfriend and I will be going in mid March. On our list is Arenal, Monteverde Cloud Forest and Manuel Antonio. How many nights should we stay at each place? I want at least two to three days relaxing in Manuel Antonio at the end of the trip. We are flying into San Jose. Any other recommendations would also be appreciated.

I would do four nights in the Arenal area, two or three nights in Monteverde, and three or four in Manuel Antonio.
