Looking to spend your days at sea in a deck chair watching the kids splash in the pool? Or would you rather be hooked up to pulleys and try your hand at a rock-climbing wall on the ship's smoke stack. Whatever the desire, you'll find everything you need on today's cruise ships. Of course, the larger, newer ships offer the latest and best facilities. Every ship provides passengers with at least one swimming pool and various, outdoor activities. Royal Caribbean has an ice-skating rink on the Voyager-class vessels. Princess and Royal Caribbean offer a mini-golf course on the top deck. Holland America has tennis courts. Many lines offer basketball courts, running tracks, volleyball nets, and driving ranges. Nowadays, there are even golf simulators on board that help you to brush up on your swing or play a round at the course you're cruising towards.
