...or WDWR, DLRP, TDR or HKDLR.
I would love to see the Foo Fighters on the Rivers of America, and Destinys Child in front of SBC. I reckon No Doubt/Gwen would rock Paradise Pier.
I would love to see someone well-known play at the House of Blues in Downtown Disney at WDWR. Whenever I go its always someone like Hanson.....the Fantasmic arena at MGM would be great for concerts if they could detach the mountain.
