I did want to note in followup to my previous comments - the December 12 3830 Shadow cruise that we are booked on has a 50% supplement in vista (non-balcony) and 75% for veranda, while the 3831 Christmas cruise I'd like to change to has the 200% supplement. The 3830 also is a 40% off silver sailing, while the Christmas has the 10%. It has the 5% early payment. I guess when they think they an sell it, they offer basically nothing. I booked the 3830 onboard for the savings but booked medallion, so it is only 25% off vs. 40% for veranda.

So the bottom line is if they want you to save, you really save, if not, you really don't. I guess December 12 is a much slower time than the Christmas/New Years cruise.
