Oh, one point about TP if you're gonna pack it.

Don't bother with the roll. Instead, buy the travel tissue packs intended for your nose.

You're not going to be wipin'n'flushin' so there's no need to be concerned about clogged toilets.

They pack much better, you use less of them.

Bonus in that you can use them for lots of other things, such as first-aid or (and here's a surprise) your nose.
