We'll be sailing out of Miami in January on Celebrity. I know that parking at the Port of Miami is $20 per day, which would be a total of $280!
There's a company called Premier Cruise Parking, which is about a mile from the Port? I can park there for $10.88 per night, or a total of $152.32. They have a covered parking structure, and have a free shuttle that runs every 10 minutes or so.
Has anyone ever used them? Comments? If you haven't used this parking facility, can you recommend one that is cheaper than the Port of Miami?
