By far, one of the best values we have ever had. Lot's of driving (3 hours each way) but when you get to the park, and on the boat, you forget all that time. We left at 6am, and didn't get back till 7:15pm. Never felt rushed.
The best part of the trip was the tour guide Roselyn. In addition to being very knowledgeable about the country, its regions and its history, she is a skilled naturalist. She knew all the birds, and "critters" we encountered, and had no trouble identifying any of the trees and flowers we pointed out.
