There are these
Glide-Ariums
They have sizes for travel/vacation enclosures.
Some use pop up kennels (like for dogs), there was a thread somewhere about it, if I can find it I'll link it here.
Someone else had a pop up kennel style kit on their website, but I'm drawing a blank on it, guess I'm just too tired atm.
Also some use cages like the starter cages from PP, not that I recommend buying one from them, but they are a good size for vacation. Martin's cages I believe have sizes that would be good for vacation cage as well.
