We went on our first ABD trip 2 years ago - to Costa Rica, and the destination was perfect for our two super active boys (then 9 and 11, will be 12 and 14 for a possible ABD trip next summer). What other ABD trips are good with active boy tweens and teens? I'd love to go to Italy but they pooh-poohed that as "too much sightseeing". Suggestions??
