@patrickrhone was 10 years ago and we were backpacking. State of accommodations may have changed. East coast was fairly run down but less touristy. With different ethnic population (i.e. black) Caribbean has historically got less state support.
@patrickrhone had a great time in Cahuita on the Caribbean coast. Sleepier (and poorer) than the Pacific but there's forest with monkeys. Also the sloth sanctuary is nearby. Sloths are cool. Monte Verde definitely worth a visit too.
