Royal Caribbean also constantly changes the pricing on their cruises depending on many factors; how fast each catagory is selling, how many rooms are left in the catagory, days left to sailing, any last minute cancellations and other factors. I've seen a particular cabin change prices 4 times in 2 weeks even though everything else stayed the same. Royal Caribbean just like any other business is trying to get as much as possible for each room while leaving no room empty. Just like the airlines and seats. Why else do I pay $49 for a flight when the guy next to me pays $149 for the exact same flight just because he booked it later/earlier/on Tuesday/after 6 or whatever.
Seems like a Great Cruise, but my wife wants to go on a 12 day in Dec 2007.
