Summer is here and vacations are in abundance.  One of the most popular types of vacation and my favorites is cruising.  Out on the open water with all of the fun, food, and festivities you can handle.

On some ships, you can practice skydiving on board, try your hand at ziplining, learn to surf or spend an afternoon ice skating.  Other ships employ a full time librarian for those times you want to curl up with a good book.  Most ships have a jail on board, so you might want to keep your craziness to a manageable (or at least legal) level!

Thinking of cruising this summer?  If so, check out some of these unexpected things you can expect to find aboard these floating mammoths.
