I stayed at the Ren last October. As a plat I was not offered breakfast coupons on the weekend, but they kindly handed me some after I asked.
As Sophie said, the best thing about the Ren is the location in downtown Asheville. If downtown is your destination the Ren is great. Otherwise, it is your standard slightly outdated Ren.
Don't get me wrong I would stay at the Ren again, but this October I think we are going to try the Bohemian.
