I might have mentioned this upthread, but I booked a hotel other than the GH at DFW last summer. My flight was delayed because we diverted to Austin and getting through customs took an hour plus. Suffice it to say, my hotel's free shuttle stopped running at midnight, so I ended up paying $35 for the three-mile taxi ride. AA ended up throwing me $150 in AA money after I told them about this, so all is good with them, but I now pony up extra money in order to stay in walkable hotels, whenever they are options (actually, I wouldn't do this at PVG because the hotels between the terminals suck, but nobody should be laying over at PVG overnight anyway).
