I just signed up for probably one of the only hotel/motels with rooms just now, and they have 9 rooms available on the nights of the 3rd and the 4th, so call NOW:

The two wheel inn at Robbinsville. 59.99 a night, 69.99 a night double occupancy, and you also get a free bike garage (not a selling point for me, but hey, I thought I'd toss it in there in case any of you plan to ride your bike down instead of your boxster!)
