EMD: I suspect you're booked at the Hotel Roanoke, which is quite a nice property, and well located, within walking distance of some nice restaurants and shopping. There is a decent Marriott in Roanoke, out at the airport. Roanoke is not a very big place, so it wouldn't be much of a commute (maybe 20 minutes - a guess) to drive from the airport to downtown each day.

I like the chocolate chip cookies upon checkin, which are Doubletree's trademark, but like you miss the association with a frequent stay program.
