Passengers can vary from ship to ship and cruise to cruise. Just ask your Cruises Inc. representative for advice on the best ship for you, based on your tastes and lifestyle. There are over 30 cruise lines and over 130 ships for us to choose from, we are sure we can find the right one for you. Cruising is ideal for people traveling alone, because it's so easy to meet other people. In fact, most ships have singles parties early on to give you the opportunity to meet your shipmates.
Most ships also have single cabins as well as single rates for double staterooms.
In many cases, the cruise line will even find you a roommate to share a double if you ask them. Pack like you would for any resort. Cruise vacations are casual by day, whether you're on the ship or ashore. In the evening, ships vary as to dress. Some ships have theme nights such as Country and Western night, or a Roman Toga party, so you could dress accordingly if you desire.
