Stayed overnight for an early flight out of CLT. Poor customer service for valet and the "Rooftop Bar." We wanted to check out their outdoor bar on the 18th floor yesterday. Our greeting was mediocre and we were not explained the "rules of the lounge." We got some fun cocktails from the bar, but the entire bar was rained out. They have cotton seat cushions that were wet and they have no bar stools. We sat in the inside lounge and the women let us know that this was only for "platinum" members, even though we are gold status. Staff will benefit from continued training on the important of positive staff interactions. We had an early flight today and used the convenient text to valet option to have our car ready to go at 4am. We got down to check out and there was no staff in site. Valet took another 15 minutes to show up. Unfortunate experience here.
