You'll be happy to know that all skier levels are welcome at ESA.
Lodging options are usually posted with a few different choices and pricing options in the same basic location.
As for the dates...there hasn't been anything specific posted yet, and the ESA website has not been updated, but I'm looking for that to be done soon.
The date your looking for Aspen-Snowmass ESA is January 10-14, 2010.
Yep, I'm just now working on getting the ESA site updated and registration underway.
In the meantime, all of this article will apply to ESA Snowmass 2010, except the dates are 1/10/10 to 1/14/10, and the price of a double occupancy room (including a full breakfast buffet) will be $185. The event price, which includes lift tickets, will be between $950 and $999.
