Carnival Cruise Lines cancels reservations made during pricing glitch 

We all want to save money and still have fun this summer. So if you were browsing the web for cheaper rooms on a cruise and found and booked those tickets, you'd expect the cruise line to hold up its end of the bargain. Right? Well, not necessarily. Some people who booked on a Carnival Cruise Line ship got a wickedly awesome deal, only for the company to come back and say, "Oops... that was a mistake, we're cancelling your rooms."
