If planned properly, a cruise can be one of the most fun and relaxing vacations you'll ever take. No matter where you go, or what you see, your hotel room will always be within reach. Here are a few tips that will help get you started:

Choosing a ship

Cruise ships offer everything from rock climbing to spa treatments so be sure to ask about ships based on your interests and make sure you choose a ship that best meets your lifestyle. The size of your ship may also be something to consider. If you're looking for more personal service, a small ship is perfect and can have as few as 500 passengers. Larger ships can hold as many as 6,400 passengers and offer more onboard activities and amenities. They also help reduce the possibility of seasickness.

Picking your cabin

Check your ship's floor plan before making a final decision on where to stay. Cabins low on the ship are the cheapest but also experience engine noise. Middle cabins have less engine noise, but more foot traffic. However, these cabins are best for those with seasickness. Higher cabins are more expensive but they also offer better views and are closer to the pools and other activities. Keep in mind that on some ships the difference in price between a porthole and a balcony can be relatively minor, so do the math and consider an upgrade!

Deciding what to bring

When packing clothes for your trip, remember that most ships are fairly casual on deck. Dining rooms usually require dress casual attire and there may be at least one formal night. Check your cruise line's Web site or ask your travel agent for more specific details. On the day you embark be sure to carry on all your travel documents including all your cruise documents, passport and medical insurance cards. Also, carry on all your valuables, anything that could be broken and anything you might want right away. Cruise ships load luggage like airplanes so prepare to wait a couple hours before it arrives at your room.

Reserving your excursions

Most ports have a variety of excursions with a large range of prices. Try to take advantage of at least one excursion per port or you may miss one-of-a-kind experiences you can't find anywhere else. You may save a little money if you decide to book your excursion at port instead of through your cruise ship. Only excursions booked through your ship can guarantee you'll return before your ship leaves port.
