What Cruise Ship/Line is the most formal?

Answer 1

CUNARD makes the top of my list, however Silver Seas and Crystal are also pretty black tie as well.

Answer 2

If you have the money to spend for the very top and best cruise lines try Crystal, Radisson, Cunard, Windstar, and Silver Sea. These cruise lines are a cut above the others because they run smaller ships (about 500 to 700 passengers) and have a higher staff to passenger ratio so you get top of the line service. They also have more amenities included in the much higher price, like all veranda/balcony cabins, tubs and shower bathroom, larger cabins, daily wine and/or champaign with meals, etc. These ships generally go to a port or two on a seven day cruise which may be
different from the normal. Prices for a 7 day cruise on these top of the line ships may start at $2500 to $3000 (vs about $1200 on the next tier of ships.). These ships tend to have a more sophisticated and older crowd and more formal dining. You wear a suit or dress to dinner every evening. They don’t pressure you to buy with art auctions and spa deals. You are more likely to see a celebrity or someone famous on one of these cruises because they are what you may call “exclusive”.
