Freedom of the Seas - the world's largest cruise ship

I have always had this question about cruise "ships" that provide you an experience similar to a holiday in Vegas - why board a cruise ship if you can simply visit Vegas or Atlantic City or whatever directly? Only the ship "cruises", those on board seem to be reliving their landlocked lives! Notwithstanding, this slideshow about the amazing Freedom of the Seas is worth viewing. For the cost of a few mts, you will most likely earn a longing to be part of the experience. Don't miss it.
