We have 11 nights for our March 2011 Costa Rica trip. We are a family of 5 including 3 teenagers (13, 15,16). We are not sure how best to divide our time so that we are not spending too much time in transit. We are thinking of 2 to 4 overnights in Arenal, possibly 2 to 4 nights in Manuel Antonio, and 4 to 6 nights in the Drake Bay area. Our flight times allow us to avoid staying overnight in San Jose as we arrive before lunch on our first day and depart after lunch on our last day. Also, we are planning to reach and/or depart Drake Bay via Nature Air or Sansa (depending on what area we are in before/after). Our top priorities for the trip are snorkeling, seeing wildlife, and zip-lining. It sounds like from all the posts I've read that zip-lining in Monteverde, while it may be the ideal location, is not worth the added travel time. Would the Drake Bay area be exciting/good for jungle and wildlife viewing? Would it be better to consider zip-lining in Arenal or Manuel Antonio? We are an adventure oriented family and will make good use of the kayaking and hiking options that some of the Drake Bay lodges include. Everything I've read about Drake Bay sounds like it would fit our family and interests in terms of lots of activities, low crowds, scenic location, etc. We are not sure whether Manuel Antonio has something unique to offer in terms of overall experience. Would there be a better area to substitute for Manuel Antonio? Should we just focus on Arenal and Drake Bay or would that be too much time in each? Thanks in advance for the ideas.
