I called, and you can book a 4A and be upgraded to a 5A, or book an 8A and get an 8D, but if you book a guarantee, it is the same price as anytime. Not really any great deals that I saw. So I am gonna wait until another better sale comes along. Can't go until spring of 2005.
Hope this helps you to make up your mind. I'm sure there will be lots of other sales. But if you find one that is right for you, by all means, book it. Then the next sale, you can book another one!
Good Luck!
