Here sitting at a sidewalk cafe in Normandy w/out much internet and only a 4" iphone but you definitely want the West Coast, I'm trying to recall the name of a national park named after some guy.... Manuel Antonio? Also, inland check out the Serapiqui and Arenal regions and if it gets too hot Monteverde.

Been twice chaperoning kids, a great experience both times.
