Disappointed
I just returned from my stay at Hilton Charlotte Center City. I was there to attend an ASCD institute. When I made my reservation in advance for two nights I was not told that the first night would be billed to my credit card immediately rather than just held for me. They did know I was attending the ASCD institute because I had to tell them when booking in order to get the institute rate. When I checked out and tried to pay for both nights with the travel credit card my school district had given me I was told I could only use it for the second night, the first night was already charged to my personal credit card and could not be changed. So now I must wait four to six weeks to be reimbursed by they district because I did not follow the district procedure. I talked to another person who stayed at a different hotel because school districts do not pay for hotel rooms in advance because they cannot afford to pay for hotel rooms that might go unused. I have travelled numerous times with my school district and have never had a problem with a hotel transfering the charges from my personal credit card to the school credit card when I checked in or out. 
In the minor complain department, no maid service and no shuttle from the airport to and from the hotel. The only transportation is a $25 taxi ride each way.
I have stay in Hilton Hotels many times, but this one was a definite disappointment. I will not be stay at the Hilton Charlotte Center City again. The Hilton Honors point you get are not worth the aggrevation.
I also had a problem with internet access. I was not told when I checked I was not told ASCD had arranged for internet access with a special code so I had to pay to get on the internet to get the handouts and presentations I would need for the next day. When I complained about this I was told the code was written on the outside of the key holder. However, when I tried the code, it did not work. The code had been written down incorrectly by the person who checked me in the night before!
