I would think that flying into Orlando (MCO) would still be the best bet. It's less than an hour's drive to the port. There may be a couple of smaller airports that are closer to the port, but they probably don't offer the selection of flights/airlines that MCO does.
If you are using Delta and go through Atlanta, Melbourne is a very nice easy airport to get in and out of, and is closer to the port. Any other airline,Orlando remains the best choice.
