Beautiful mansion, 45,000 sf, 100+acres of grounds. Certainly the capacity to do this event, and unlike a hotel, you would have the entire facility to yourselves.
Contact Pat Prather, wedding coordinator, at 859-255-2777, Chef Ed Valente or General Manager Gerald Marvel.
I worked there for 2 years, and can attest to the quality of the facility and their top-notch culinary and service teams. This was also the location for the wedding of Alecia and Jared Pace, as seen on the Ellen Degeneres Show in 2006.
