What travel cages do you guys use for quick weekend trips? I'm visiting the in-laws

Thanks!

I use a dog tent, like the one in this link:

The only issue with that is that it doesn't have a poop tray, instead I put a liner (I had one made for it, that is washable), and take it out in the morning. I hang toys and pouches from the top and the sides (which are all mesh). Before I was using one of those cages that you can fold, but it wasn't very big, specially now that I have 4 gliders. This is very big and easy to carry around.

I've also hear good things about the weekender (sold by The Pampered Glider: http://www.thepamperedglider.com/travel-accessories) and the likes.
