It is amazing how silly you people are about vacations.
Going on a cruise can be exploring the world because you'll go to places you never been. While a lot of them are tourist traps, so can pretty much any city and other place in the United States. Of course, if you're not smart to start with, then you deserve what you get.

Until you experience the available packages, you shouldn't comment on the entire cruise industry. I've been on several and have visited places over the world that I might not have gone to. Many packages allow you to make excursions past the Welcome Americans and your Money ports, you just have to see what's available.
And while they can be expensive, they are not boring or even gay (unless you go on the ones that pissclams does) and you'll be surprised at what you can do.
So be an adventurer and stop listening to the unambitious tards that frequent these boards.
