I had an absolutely amazing time in Costa Rica. Not only was the country beautiful, but the locals were hospitable and respectful to volunteers travelling abroad. To top it all off, the staff was absolutely amazing at making sure everyone was comfortable. I got the opportunity to travel the country-- both with CCS staff--and with the local friends I made. For me, everything was perfect.
If you do get the chance to visit, make sure you are prepared for some adventures such as zip lining or repelling off waterfalls. However, one of my favorite vacations was the 3-day relaxing time at Manuel Antonio beach. It is something I'd recommend to anyone going--just watch out for the monkeys.
