I've been reading this forum for a few weeks and found some great info for our summer 07 trip. We're saving up our choice priviledge points for 8 nights at a Comfort Inn which is in all 3 of these towns. Would it be best to split our stay and start out in Rapid City for a few nights to see the Badlands & Devil's tower? Then move to Custer or Hill City (which one?) for Mt Rushmore, 1880 train, Custer Park, Caves, Black Hills, and Hot Springs? Or any better plan of cities with a comfort inn close to what we want to see? We'd also be open to renting a cabin if I could find one for under $500/week but all I've found so far is the same price as the hotel room and I know we'll have earned enough points for 4-5 free nights by then.
