Are dining reservations necessary prior to sailing?
Not necessarily. Most cruise lines now offer flexible dining arrangements that no longer require you to choose between first (early) or second (late) seating. Cruise lines that do request your preference do so on a first come, first serve basis. So be sure to call as soon as you can to guarantee your satisfaction. Some cruise lines have fancier alternative dining restaurants that require reservations be made and a service charge paid for their use.
