Catelina, If you enjoy leisure, good food and enterntainment, you will enjoy ships. I even cruised from Moscow to St Petersburg several years ago. If you are prone to seasickness, you can get medications or wrist bands that help prevent sea sickness. Many cruises even have midnight snacks, and excercise rooms.
My last cruise was on a small yacht two months ago to the Galapagos Islands. The previous cruise was in December of last year to South America from Valparaiso around Cape Horn up to Buenos Aires. I enjoy cruises for several reasons. They are comfortable, you can enjoy good food, it's very relaxing, and the visits to the different ports are always interesting. If you have any questions, I will be happy to try and answer them. c.i.
