Cruise ships get some unusual questions from their customers. Here's an amusing sample collected by Celebrity Cruises and published by the trade magazine "Travel Weekly":

* Does the elevator go to the front of the ship?

* Why does the ship rock only when we are at sea?

* Does the ship generate its own electricity?

* Will I get wet if I go snorkeling?

* Does the crew sleep on board?

* Is there water all around the island?

* How do we know which photos are ours?

* What do you do with the ice carvings after they melt?
