Manu money

I was offered at the last minute last night an 8 day visit to the Manu biosphere reserve for only $580. It's usually $800 or more for that kind of thing. I was tempted, but it would have meant deciding at that moment, leaving this morning on a 10 day bus ride, and, well, spending $580, which is still too much money for me. Argh, I am so frustrated by that. I really wanted to go to Manu. It's supposed to be the last pristine jungle environment left on Earth. They have a parrot clay lick!
