I'd expect most mid-range or higher hotels would be willing to store bags for you, if you ask when making reservations. (Mid-range and up meaning Holiday Inn, Country Inn and Suites, Hampton, Marriott, and their various brands.) Most airport hotels have their own shuttle buses, although it might take two trips to get everyone and their bikes moved. So pick a few and ask. Twelve bags might be a lot, but so's 18-36 room-nights.
I cringe when I read "bike bags" and "wrapped bikes," though I've heard it's common in European travel. You might get lucky when American baggage handlers start moving them, but there was a luggage commercial some years back that showed great apes throwing and jumping on top of the advertised luggage. Most travelers I know think that was illustrating the hub they usually fly through. At least if you're staying two nights you have time to work on fixing any problems caused by travel and mis-handling.
