The one activity I will go out of my way to avoid is arcade games. Thankfully, they're becoming easier to avoid at WDW, but I just cringe at the idea of spending time in an arcade when there's a perfectly good one (with better games) near our home. DS is drawn like a magnet to them, and I just run interference every time I see one.
(I also hate running into places where they've got video games to play in the parks. We ran past those Infinity 3.0 consoles in Launch Bay so fast that my son didn't even see them. I'm sure they're great if you don't have the game at home or want to try it out. But we play plenty at home, so I hate the thought of using valuable time playing a game we have at home!)
