Disappointed w/ Events Manager
We just had our daughter's wedding in Charlotte and decided to use the Renaissance Charlotte South Park Hotel as the hotel for our out of town guests. 
Let me first say the hotel was great and the staff was wonderful. However, be wary of the Events Manager. We thought she was wonderful and was going to take great care of us and our guest.
We made two specific trips to the hotel, as we also are from out of town, to meet with the Event Manager and to ensure we had all necessary arrangments made.
We had a simple request to ensure all of our guest who booked in the room block we arranged would be on the same floor as we, the hosts, would be. Two primary purposes so that it would be conveninet for them to enjoy the hospitality room we were hosting and to ensure we did not distrurb other hotel guests who were not part of our group with noise from our celebration.
We also had the bride to be staying in the hotel and wanted to ensure she stayed in a room away from all other guests to ensure her privacy and ability to rest well the night before the wedding.
Word of caution. If you use this hotel, be sure the Event Manager passes all the arrangements you make to athe appropriate hotel stay for execution.
Despite the planning, the Event Manager never passed the information to the front desk. Totally dropped the ball. We should have suspected something was wrong when we checked in. The front desk was clueless to the arrangments made for our rooms and hospitality room. 
All of our guest were placed on a different floor then we were and in fact were on the same floor as the bride to be!
All had a good time, but what a disappointment. 
And all the hotel had to say was sorry. Sure, we received a personal phone call from the Events Manager explaining what happened, offering an apology. But that was it. Essentially, we're sorry but too bad, too sad. They had are money (of course you have to pay in advance).
We'll never use this hotel again and strongly suggest caution should you decide to hold an event at this hotel.
