The Ecolodge is a great place to get away from the everyday. I have never returned from a vacation more relaxed. I loved the grounds and the rain forest. The guides were fabulous on all our tours.
Things to keep in mind - it is remote. We used the city bus system to travel to the hotel and spent 7 hours getting there from San Jose International. Spend the money and hire a driver if you are not renting a car unless you have lots of time. Thier driver is fabulous and will be more than happy to stop along the way or point out interesting sites to you as he drives. There are no tv's, radios or even electric plugs in the rooms. There is no air conditioning but you don't really need it. Take a sweater for cool evenings on the porch.
Overall if you are looking for an out of the ordinary place to stay from all the hassles of the current society, this is your place!
