Jane,

Since I live in Asheville, I am of course game for the Biltmore Estates.
I'll do some checking and see if I can save us any money on tickets or dining. Best I'm seeing at the moment is $10 off if you buy them ahead of time online. Also, They do offer group rates:
Group Sales at 800-211-9805 or groupsales@biltmore.com. If we can get a head count, I'd be happy to negotiate a group discount.

See ya in the fall!
