For those who have tried the Rainbow, how big is it inside? TT's website lists it as 1-2 person, which sounds workable for what I'd like; I'm looking for a small tent for myself and my fiance. Can it fit two sleeping pads side by side? We're both slender people. Also, how does it do in the rain? I've read a few reviews, but some of them are older. Does the clipping bathtub floor actually work?

The other tents I'm considering are the Rainbow2 and Six Moon Designs' Lunar Duo. They sound a big larger than I'd like, though.

Thanks!
