Is there a way to get here from the Amtrak station in Clifton Forge, Virginia?

They do offer pick up from Amtrak just call the Omni Hotel and set it up.

Yes

They do have shuttles. I just don't know where their pick-up stops are. Give them a call they are wonderful.

Call the homestead because they may have a shuttle

I don't know, I have always driven. You might contact the Homestead and ask. They are very accomidating.
