Marc's Tree House.... This deserves it's own section as it definitely made the experience.  Tree House #6 was right on the river and fortunately had an en-suite!  The windows were just wooden rails covered with a roll-up canvas, the walls were made from a bunch of bamboo sticks topped off with a thatched roof and our beds were covered with mosquito nets (although we never saw one).   It was AWESOME!!!   We had a few visitors (lizard, frog, various insect creatures) oh and the Monkey's jumping on the roof at 5:30am for our wake-up call!  Anyway here are some pics from Marc's.
