We took my son's Gameboy while we were in Epcot last week. We only ended up taking it out of the backpack once while we were waiting in line for Living Seas. I don't think I'd take it along to the theme parks next time. As others have mentioned, though, it sure comes in handy on the plane and in the airport!

I can tell my own kids to turn off the noise; I probably wouldn't tell yours.
