I hate the hassles of airline travel, so don't get out much (been years since I've been to Denver).
Where to stay? (Best to stay at the Marriott or close by?)
How to make best use of the available time?
How can I link up with other ACers? (OK, so I'll break down and buy a T-shirt, anything else?)
Cheaper to take taxi or shuttle back and forth from airport?
Any chance to find a roommate to spilt hotel room?
