We just got back from the Biltmore and were not impressed. We were moving our son into college and did not get to take advantage of the beautiful pool, which is incredibly large, or the golf. We did use the very nice gym one time.
When we checked in, we were given a room on a hallway that had a very bad odor. We called to complain and were told they would send a technician "right away." Twenty minutes later, we were told the same thing. Forty minutes later, a technician finally showed up and said that they knew there was a smell (I guess they counted on people just dealing with it). We finally went to the front desk to complain, and after having to insist that the room was unacceptable, we finally got into a room without a foul odor. The rooms were nice and spacious.
The food service at the restaurants were horrible. We had to wait incredibly long amounts of time to get served on two separate occasions (out of 3 meals eaten there). Again, we were told our food would be there "right away." Apparently, there must be some training to use those words, even when they don't mean it. It was clear that they did not have the restaurant staff to service the amount of people at the hotel. At the 19th hole restaurant, we had to go to the bar ourselves to get served water. And, the food at the Fontana restaurant was horrible - in addition to being very delayed. It was the worst Italian food I have had in many many years. The only positive was that the manager did comp the meal for my family of 4, of course, we barely ate any of this food. And, I would have much rather paid for a meal that was edible and timely.
The one area that did have good service was the bellmen.
With a son at college in the area, I was disappointed with this experience since I would have real qualms about going back. Hardly the service you would expect from a hotel with this name.
