Explorer sails from Miami. Cab, Super Shuttle or cruise line transfer are all options. If there are 3 or 4 of you, a cab might be less expensive, assuming you can all fit (plus your luggage) into one. Super Shuttle charges per person -last time I used them (summer 2001) the charge was $12.50 per person from MIA airport to a Miami Beach hotel (slightly farther than the cruise dock). YOu can reserve a Super Shuttle ahead of time via their website or phone number (sorry, I don't have either handy). For ease of use, I might recommend booking the cruise line shuttle back from the ship to the airport. I'd say either-or for getting from the airport to the ship.
