Each guest has the option to carry their luggage on board or check-in luggage prior to boarding. Luggage may include suitcases, trunks, valises, satchels, bags, hangers containing clothing, toiletries and similar items.

You are allowed to bring a quart-size, zip-lock bag of liquids, aerosols, gels, creams and pastes though the checkpoint in carryon luggage. These combined items need to be less than 3 ounces. More information from the TSA. So the 3-1-1 rule is the TSA's quick reminder: 3 ounces, 1 quart bag and 1 bag per traveler.

On cruises of 6 days or longer, no more than two bags, per person. Each checked bag and carry-on bag should not weigh more than 50 pounds and, when lying flat, bags must not exceed 16 inches high, by 24 inches wide (the length of the bag is not a factor). For security screening purposes, all luggage should be unlocked.

You should average two outfits per day, as you'll wear one during the day and one at night for dinner. I find that I like to re-wear at least two or three outfits at night to save space. Plus, I just don't like having to plan seven different outfits for each night. This, however, is a personal preference.
