Port Everglades parking is $12 per day. I parked at Amerisuites on 17th for 20 days after staying there the night before. You can also go to www.airportparkinglots.com. Parking is $5 a day. I don't have any experience with them but will try it out next month (since I am driving down day of cruise, dont' want expense of hotel).
