In cruising, one size definitely does not fit all. What's appealing to one passenger may be unacceptable to another. The ship you pick will determine the type of accommodations you'll have, what kind of food you'll eat, what style of entertainment you'll see, and even the destinations you'll visit. If you don't enjoy your ship, you probably won't enjoy your cruise. The most important factors you'll need to consider when booking a cruise are the size of the ship, the type of cruise line, and your cabin.
