On Priceline, Cocoa Beach is NOT part of the Orlando area. If you type in Orlando, you will get WDW, Universal, MCO, Fl. Mall,etc. If you type in Cape Canaveral, they will ask you if you want Cocoa Beach, Daytona, or whatever (there's another one too.) They have no hotels officially listed as Port/Cape Canaveral. If you type in Cocoa Beach, you will get Cocoa Beach.
If that's as clear as mud (sometimes I'm the only one who understands my explanations), feel free to write me and I'll try to explain. The bottom line is that if you want a place as near to the port as Priceline will go, you need to request Cocoa Beach as the city.
