We (my husband, me and 2 children) will be arriving into Liberia and staying 5 nights at Westin then transferring to Arenal for 2 nights before a departure out of SJO. We are debating on renting a car from Westin to Arenal or Arenal to SJO. If we were to drive ourselves on one of those routes, which would be more wise? We like the idea of being able to stop and see some sights on the way. Would a driver do that for us if we hired someone?
