For those adventurous travelers who think knowing where you're going is old-fashioned and boring, there are now web sites for you, according to the Huffington Post. These new web sites let traveler's book blind travel.

They aren't referring to the type of blind travel booking done on web sites like Priceline or Hotwire, where you are narrowing your options to be within certain parameters, like, say, the city you're booking in.

The new blind travel booking web sites let users book an entire vacation, including the destination, flight and hotel, based only on a vague idea of the users travel preferences.

One of these new web sites is FlyRoulette.com, which launched earlier this week. The site lets travelers book the aforementioned vacation between 48 hours and 12 hours before their flight departs. It's a great option for those who have trouble making up their mind in advance.

Users provide the web site with their maximum budget, their ideal trip length, luxury level, ranging from "high roller to "open minded," and trip theme, which includes choices such as "fast-paced and random" or "weird and exotic. The web site does everything else.

Think about how difficult it would be if your friend asked you to book them a trip based on only those criteria. It would prove to be rather difficult.

GetGoing is a similar site, but with slightly more certainty, but only slightly. This site does allow users to choose a definite departure city and a general region of arrival, though that can be as vague as "Africa & Middle East" or "Beaches & Sun," which doesn't really seem that narrowed down. The site then prompts users to choose two cities, such as Cairo and Dubai, from which they will choose one, though you won't know which one until you book it.

For anyone wondering what would make people travel like that, it's probably for the discounts, which are up to 40 percent.
