Looking for some info , sailing on Voyager 2/11/2001,
I've upgraded at the gate on many an air flight ,
Is it possible to upgrade on a cruise ? if anyone has, generally is the upgrade rate substantially less than published rates?
I know you can upgrade if space is available, but it is not free, and in most cases it is more than what you would pay to upgrade before sailing. I would recommend you call you TA and ask them to check. It might be a little more, but not compared to the price you would have paid if you had booked it in the first place. You might want to get an idea of how much it is worth to you-- for ex an inside to outside, or outside to verandah, etc. You can even wait list for a room you want, then you have the option of taking the upgrade or not.
dont expect a free upgrade unless you booked a guarantee or run of ship.
