I think there's some leftover egg crate at work. I'll see if it's earmarked for anything, otherwise I'll pick up something cheap for this one trip.

Hadn't thought of earplugs, that's an excellent idea! There's supposed to be an 11pm sound curfew in the area I'll be in, but I hadn't thought of tent rattles, etc., and I don't know how well the curfew is enforced.

Thanks!
