Buy tickets on line and save $5. THe wife and I visited a couple weeks ago; had a great time. It is awesome.
I recommend the additional $10 per for the headset and "guided tour". You punch a number for the room you are in and it tells you all about it.

Worth the $10 each.
We did the house and Vineyard in a day. It was enough for me. We drove throught the garden on the way to the vineyard, it is nice too.
We stayed at a nice (but not top of the line) B&B called a Bed of Roses (
www.abedofroses.com). It was good. I told Naoko when we get "flush" again we would stay at the Grove Park Inn. That place is on the Asheville Trollley tour, which is also cool.

Enjoy.
