Your literature emphasizes the local guides more than any other company I know. I'm on a holy crusade to get people to understand how important the guide is. Walking alone through the forest when the animals are not cooperating is usually boring. Walking through the forest with a great naturalist guide is akin to experiencing a work of art, even if you don't see a single beast. The great guides are part biologist, part performer, and part mother.
Guides are where the most value can be added to travel.
A healthy evolution of the vacation industry demands that the marketplace values guides more. We need kids dreaming about being guides when they grow up. We need old guides who keep at it until they retire. I'm sorry if I got carried away here. Ecotourism to many implies barebones accommodations, maybe even discomfort, and minimal service.
