I stayed at the CY last year during the festival for 5 nights on points. The points are a fantastic value considering it is a category 5 and the going cash rate for hotels. I even managed to find a pointsaver rate. The location could not have been better, either; easy walking distance to the grounds as well as most other sites in the city. I would definitely recommend this over the Ren or FS, you are not going to want to deal with public transportation afterwards.
