Pay Ahead for Parking: While most terminals offer ample parking space, prepaid parking guarantees you a spot.
Check In Online: All major cruise lines make it easy to print out boarding passes and fill out emergency contact info and immigration forms in advance. You can also sign up online ahead of time for shore excursions and spa treatments.
Drop Off Bags First: Before parking, leave your bags with porters at the pier, if possible. Just be sure to first attach to your luggage the special tags that come with your cruise tickets. That way, you can walk or hop a shuttle to the terminal sans heavy bags.
Don't Arrive Too Early: Chances are, previous passengers will still be leaving the ship, making for congestion. The port is less hectic at the embarkation time listed on your ticket.
Join the Club: Membership in the cruise line's frequent-guest club tells the company you're a special customer, even if this is your first cruise with its ships. After a few cruises with the line, you'll be eligible for the shorter lines with priority check-in.
Bring Your Passport: Americans cruising from the U.S. to the non-U.S. Caribbean, Mexico, and Canada aren't required to have passports until January 2008. But if you've got one, bring it. There's likely to be confusion at foreign ports, and having your passport will only help. Also, if for some reason you have to fly home from a foreign airport, you'll need a passport.
