wendy- As Sonny has said "I think you're getting your reathers all fuffled for nothing." (Or something like that)
Bear this in mind - Your scheduled cruise date is Nov. 29,2009 - You are at the 90 day payment due date for most cruises of 7 days or more! If you have just done this it will make little or no difference!!!
At this point in time- if there is a price drop you can always contact your TA for an adjustment - in many cases the cruiseline might give you a credit on your shipboard account!
Bon Voyage,
