Binding aside, you might be able to get some privacy by bringing a single-person backpacker’s tent. They’re small & light, and you can create any number of polite cover stories about it - sometimes you need frequent nighttime bathroom breaks and don’t want to disturb your tentmate with constant zipper noises, or you’re worried you’ll snore, etc. That way if you’re comfortable sharing a tent you can do so, but on nights you need a break, you can set up your own tent for privacy.

Also, that sounds like a great trip!
