Recently stayed here for a large conference of over 500 people for a Government agency. I would highly recommend the NCC for any large or very large group. The rooms were small, but very nice. The food was included in the contract price and was cooked on site. It was really as good as any top level set-down chain restaurant. Reminded me of an Outback or Olive Garden style. There were miles of nice running paths and a nice fitness center. The conference facilities were comfortable. I never left the building the entire time. The only downside that I could see were the small rooms, but for me there was so much to do in the evenings, I only slept there anyway. I defiantly recommend the National Conference Center.
