I'm getting into Denver early on the 5th. I can scope out some stuff and suggest some places for lunch or dinner.
The closest hotel to the convention is the Hyatt.
The Sheraton is the party hotel (lucky Roger!) and there's a
Making Light party on Friday night somewhere in the Sheraton, I hope to go.
I have a reservation at the Hyatt at the convention rate which I can transfer to someone else if contacted before this weekend, otherwise I'm canceling the reservation as I've decided to share a room elsewhere with some friends - The room has two double beds but it's not a suite (it's about 400 sq ft room) supposed to have a city view and be somewhere above the 4th floor. The Hyatt is about 3.5 blocks from the convention center.
Weather for Denver next week looks to be hot. Average temps for the convention days are 85F to 97F. Low chance of rainfall. Humidity is usually low as well - 11% today for example. Keep hydrated. Also, if you have had any altitude related issues (I get migraines), don't forget that Denver is called "The Mile High City"
