Hi, Helen,
The gentleman teaching faceting at Wildacres in April 2009, Steve
Weinberger, also teaches that course at the nonprofit Gem Cutter’s
Guild in Baltimore, Maryland. I believe that this spring, their
faceting course will be weekly – details not posted yet – but it’s
possible it might be taught on a single weekend. Even though the
faceting class is not posted yet at their site
(www.gemcuttersguild.com), you could see their other classes to get
an idea of pricing, which in my opinion is very reasonable. As a
nonprofit, part of their income is donated to grants programs for
local grad students in the earth and planetary sciences (or geology?
I can’t find details on their website, but a collection is made at
every monthly meeting for this fund, and the Guild matches the
donations).
I should add that, almost regardless of what we see on "The Wire,"
Baltimore actually has a lot to offer as a tourist destination. 
And Baltimore is only an hour from DC and the Smithsonian’s
collections.
