Epic is primarily a kids' ship (at least during school holidays). The revamped, complimentary children's and teen's program, with age-appropriate play, sports and activities for tiny cruisers aged from six months to 17 years (plus the fantastic onboard water park), means Epic is a natural pick for families; you'll see plenty of youngsters during school vacation. Outside of that time, expect adults in their 30s to 50s, with a smaller number at the opposite ends of that age spectrum.

Casual attire is part of the Norwegian experience, so you can leave the ball gowns and tuxedos at home. During the day, cruise casual is the way to go, with shorts, Capri pants, jeans, t-shirts and sundresses for women, and for men: shorts, jeans, polo shirts and so forth. For the evening, there's not a great deal of change as far as Norwegian's recommendations go, with casual dresses, skirts, pants and blouses, summer dresses and "tasteful" jeans (no rips, cut-offs, acid washed etc.) suggested for ladies, and casual slacks, "nice" shorts (pressed, longer in length), polo, sports or button-down shirts for men. The only attire not recommended in the main dining area is beach-style shorts, although children under 12 can wear the aforementioned "nice" shorts in any dining venue.

That said, on our cruise quite a few passengers upped the sartorial ante after sunset, especially at the specialty restaurants. There are no official formal nights, but every evening one dining venue is designated "optional formal" and you might even spot the occasional tux and long dress. Typically, you will more likely see a jacket, shirt (with or without neckties), dress slacks and closed-toed shoes for the men, with women favoring cocktail dresses, elegant skirts, pantsuits and blouses over evening gowns. Cruisers might also want to pack an all-white ensemble for Epic's weekly White Hot party in the Bliss Lounge.

Norwegian charges a "service fee" of $13.99 per person, per day, for passengers booked in standard cabins and mini-suites. Those in suites are charged $16.99 per person, per day. Cruisers wishing to adjust or remove the charges must fill out a form post-cruise to request a refund.

Norwegian recommends that suite passengers who use butler and concierge services tip according to the level of service rendered.

An 18 percent gratuity will be added to all bar purchases and services in the spa and salon.
