I just got back from a week in CR with my 12-year-old son, and I can't say enough great things about what Costa Rica Expeditions did for us. They planned the whole trip, all transfers, hotels and activities. We were escorted by professional and friendly people from the moment we walked out of the airport until we walked back at the end of the week. We stayed at CR Expeditions two properties in Tortuguero and Monteverde and both were very beautiful and comfortable and the staff were extremely friendly and caring. For example, after returning from every hike or boat trip we were greeted by smiling staff members offering us fruit drinks and cold towels. The most remarkable part of the trip was our naturalist guide, William Granados, who was with us through all of our travels in CR. He knew everything about everything and explained it perfectly for my son and for me, he made sure that we got everything we wanted at the resorts, and is just an all-around great conversationalist and great guy. The most remarkable example of the service we were given was when we’re starting the long drive/boat ride from SJ to Tortuguero, William had figured out that the highway would probably be blocked by a taxi strike and arranged a flight to get us there.
I don't think I've ever rated anything online, but I feel a huge debt of gratitude to these guys. The heading here is "Private Day tours" and they planned our whole, trip, so I might copy this review in another category.
