But you don't have to buy a tuxedo just for the trip. If you do want to dress to the nines, many ships offer tuxedo rental services. Even on the most formal of ships, a dark suit and tie are fine for the dressiest occasions. Cruising is ideal for people traveling alone, because it's so easy to meet other people. In fact, most ships have parties just for singles early on, so you can start to be involved right away.
Most ships also have single cabins as well as single rates for double staterooms.
In many cases, a cruise line will even find you a roommate to share a double if you ask your I-cruise Customer Service Representative. Most ships have 110-volt outlets in the staterooms. But do check with your I-cruise Customer Service Representative to be certain. Many ships will supply hair-dryers in your cabin for your convenience. Some ships' dining rooms can accommodate all passengers in one seating.
