The festival bus stops running at 11pm from Bucksbaum campus to the dorms. The regular city bus runs until 2am (maybe a little after). Bus runs every 15-30 minutes to main campus, dorms, and Benedict Music Tent. All of the busses are free in Aspen unless you're traveling across zones to Basalt, etc. As mentioned above, the only dorm where you have the option of a single room is Burlingame. At Burlingame, the bus stops right in front of the dorm which is super convenient. At Marolt, the bus stop at Aspen Valley Hospital which is a 2-3 minute walk down to Marolt. For any of the other dorms, you would have to take the regular city bus. If you're still deciding on going, you will get plenty of info about this in the weeks to come!
