T.S.
I don't know about the availability of the homes, but I used to work for a property management company in Summit County (most of the homes are in Breckenridge). Some of them allow dogs and some of them don't, so you would have to check it out. I don't know if these would be out of your price range (I know they are out of mine), but worth a shot. Also, I know you are looking for next weekend, but the rates go down on Sept. 3rd for the fall season. Anyway, the website is: www.riverridgerentals.com
