Oh yes, my boys (including their dad) enjoy playing their game in the hotel room. In fact, they stay up until the wee hours of the morning playing their game. We've never had a problem with housekeeping "borrowing" it. They do however take it down and put it back into the suitcase as to not tempt anyone. They've been taking their game for years and we've never had any problems.

If you guys don't have the portable tv's for the car you can always bring a small television and buy an inverter that plugs into the cigarette lighter. This is what we did before the portable tv's came out. This way they will have unlimited amounts of fun in the car. They aren't too expensive and you can use them for a few years as well.

Can they watch movies on the XBox?
