If you fly you have to rent a car when you get there anyway. I'm going by charter bus just for one day. $79 includes the bus, door prizes, snacks, and the ticket into the Convention Center show. PLUS, the bus lets us out and picks us up right at the door to the show. Then we can take the shuttles everywhere else.
If you've never been there before, a sandwich and small drink will run you about $10 but the shuttles are free. There's a great but pricey seafood restaurant just SE of the museum, the painted flood wall (SE of the museum) is worth seeing and the whole show is fantastic.
Also, go online to Quilt In A Day and print off your 30% off coupon. It's good at Eleanor Burn's tent, store, or barn by the tent in Carson Park.
