We recommend that you look at the details about lodging and how to get to Crested Butte before making a reservation, but if you're in a hurry you can just call the Crested Butte Chamber of Commerce at (800) 545-4505 and they will help you make a reservation. Remember to ask for a reservation in the town of Crested Butte, and not on the mountain, in order to be close to the conference location. However, in the Summer there are always more rooms available on the mountain than in town, and the bus is very convenient to get from the mountain to town.
If you're on a budget, try the hostel or ask the Chamber of Commerce about camping.
Here's a page of Airline tips.High-speed Internet is available in the conference location and at several locations within easy walking distance of the conference location. Many lodgings provide Internet access but you should ask to make sure.
Restaurants: This is a reasonably accurate list (but note that the "lodging" section of that site is only for on the mountain, whereas most people prefer to stay in town for workshops and conferences). Here is a more colorful (but not completely up-to-date) description of many (but not all) local restaurants -- look down the page until you find the "in town" section.
