Hi. We are planning a trip to Costa Rica next march with 3 generations, very adventurous grandparents and kids ages 5 and 7. We have to go to Arenal b/c the 7 year old loves volcanoes, but it looks like Monteverde doesn't have that much different to offer, and we are choosing between that and some beach time. Any suggestions? The 5 year old (4 now but 5 by then) is not a great hiker, so we can't plan anything to rugged. Thanks alot.
