Sounds like a lot of painful fun. Two weeks of climbing in Colorado sounds dreamy, but this flatlander would need a year's worth of training to be ready for something like that. Our little 500 ft hills make those mountains giggle because they're so tiny and cute.
Have a great time! I hope you can find someone to go along with you. Can they not randomly put you with a roommate to help defray the costs? Surely someone else is traveling solo and would like to share a room.
