We're planning to travel to CR for 14 nights in February 2014. Our travel party will include my parents, my husband, me, and our then 1 year old and 3 year old. As of right now, our plan is to fly into San Jose, possibly spend the night there before spending 3 nights in Manuel Antonio. From here, we would like to go to Monteverde and Arenal before finishing our trip in Guanacaste. I'm trying to figure out how much time we should plan to spend in each place. I was thinking 2 nights in Monteverde and 1 night in Arenal to allow for daytime travel, but it seems like more people stay in Arenal for longer based on the vast number of accommodations. Will this be long enough in either place, keeping in mind we will have very young children, so we won't be able to be over-ambitious.
