i'm looking, too. haven't found anything close, so i'm resigning myself to renting a car. email me (ruffian@u2email.com) if you find something out. I'm also interested in finding people interested in sharing a room and/or rental car. I'll be going to both shows.
editorinchief, there is a thread under fan gatherings for glendale that discusses hotel options, but i still haven't found anything...
