Where can I find a luxury ecotourism destination where I sleep in the rainforest?

traveller4567 asked:

I’m specifically looking for hotels or resorts where I can have the experience of sleeping in bed while the rain falls in a rainforest or other eco destination. I would like the room to have open walls or somehow blur the line between indoors and outdoors. I’m looking for something in South America or within economical reach of Canada.
