Don't know about the airlines. Call a local travel agent. Trust me you can get it cheaper than online. Or on the phone with the airline. When I needed to go to CA in a hurry. The travel agent got me round trip tickets on two day notice for 600 from Cincinnati. The have tickets they have to sell. Plus they may get your business in the future. The airlines would not drop below 1650 on short notice.
Stay at the Red Roof Inn. It is right outside the gate so to speek. 1/4 mile or so.
