Very disappointing. I'm visiting my parents from out of state and my mom and I were looking forward to a cardio dance class together. Despite the front desk person knowing my parents by name (they're long time members), she did not allow me to pay a drop in fee without an ID. She did however suggest that we make the 10 minute drive back to the house, get the ID and come back for the end of the class. Pay a full drop in fee for half a class (especially when it would have been my mom's first dance class, therefore making her miss the intro and warm up)? No thank you! They just lost my drop in fee and any future visits. Shame on 24 Hour Fitness Boulder Hwy for their poor customer service!
