It may not be ideal, but it seems like they'd be OK for a few days. If you're taking the tent, just make sure they can be out and playing in it as much as possible while they're awake. It seems like if your choices are either having them in a small cage for a few nights or leaving them home in their large cage and hoping someone cares for them properly, the first choice sounds pretty good to me. I guess I think of it likes humans camping...you stay in a tent probaby smaller than your bedroom for a few days but you're out of it when you're awake and in it while you're asleep. You take along your essentials for those few days and most come out of it just fine! I say "most" because I HATE camping!
