BC also has very long hallways. We stayed CL last Sept and OMG the walk just to the lounge was ridiculous and I don't mind walking!
BWI also has Bellevue Lounge where you can refill your mugs and buy pastries as well as fill mugs at Boardwalk bakery and get breakfast sammys, oatmeal, pastries, salads, sammys, and more!
While SAB is a big feature for the BC; BWI has the Keaster Coaster if you or your kids like water slides..
