Demographically speaking there is no "typical" Carnival passenger in terms of age or income, although many fall in the middle income range and are attracted to the reasonable rates. Many passengers are between the ages of 21 and 45 with large groups of singles, couples and families.

Most cruises feature one or two formal nights; a dark suit or formal attire is suggested -- most men opt for suits. The dress code for the rest of the evenings ranges from sport coats and ties to resort wear. Otherwise, dress is casual during the day and a bit dressier at night. Carnival's material asks for "resort casual" for dinner in the dining rooms, and most people comply. If you look presentable, jeans are not an issue. No tank tops or shorts allowed in the main restaurants for any meal.

Carnival recommends $12.95 per person, per day, for gratuities ($13.95 per person, per day, for those in suites). The guidelines allocate a portion to dining room services, cabin services and alternative services, which include kitchen, entertainment, guest services and other hotel services. The amount is automatically added to your shipboard account, but it can be adjusted in either direction at the guest services desk. A 15 percent gratuity is automatically added to bar bills and spa treatments. Tipping a couple dollars for room service at delivery is appreciated by the service staff.
