We took a cruise out of Port Canaveral and stayed in Cocoa Beach the night before the cruise. We used a Mears shuttle to take us from the airport to the hotel (which was a stone's throw from the beach) and the cost was minimal. I don't remember what it was, but I know I wouldn't have booked it if I thought it was pricey. I'd imagine Mears could pick you up from WDW for an additional charge. If you want to spend a night at the beach, you could utilize ME to take you to the airport, and then have Mears pick you up from there. Or vise versa. We hate renting cars and driving on vacation so even though this sounds like more work, it was just easier from us. Also, Cocoa Beach was just under an hour from the airport.
