Don't know where you are staying there, but I was surprised to find that many mail order houses, B&H especially, will not deliver to a motel. I buy it in advance, send it FedEx or US Mail, shoot it, and send it home if I can't develop it there. It wouldn't be a bad idea to bracket, divide and send two shipments by different carriers. It probably all depends on how important the pictures are to you. Film in the camera and oil in the engine are cheap compared to the alternatives.
Burned and been there.
