If you ara planning a trip to Costa Rica I strongly suggest you use the MEMO Adventures. We were staying at a 5 star hotel and used their guides with great disappointment.
We heard about MEMO and went to his website at www.memo-adventures.com., booked the canopy & hot springs tour and it was GREAT. He wasn't on a schedule and was very flexible to our desires. We had such a great experience with him we booked other tours....and even our ride back to the airport! He even took money out of his pocket and went to his recommended dive company to pay our deposit for our diving at Catalina Island. He was VERY PROFESSIONAL, and helpful solving all our problems. He spoke very good English and provided us with "a look at the culture of Costa Rica" with a lunch in a local village, which was very authentic.
GREAT GUIDE, GREAT SERVICES, GREAT ADVENTURES!
