The most important choice you'll make when choosing a cruise is the ship. The ship you choose will determine what kinds of sleeping quarters you'll have, what kind of food you'll eat, what kind of entertainment you'll see, and even what ports you'll visit. If you don't like your ship, you won't like your cruise. The right ship is one that makes you comfortable. Every ship has its own personality, depending upon whether it was built for ocean cruising, yachtlike cruising, coastal cruising, or expedition cruising.
Big ships are more stable and offer a huge variety of activities and facilities.
Smaller ships feel intimate, like private clubs.
