Back in December 2008, I was upgraded from a SPR CAT 10 to a CAT 7 without any phone call. I found out when I looked at our luggage tags. I guess anything is possible.
Unlikely as you have book a specific room and have already been "upgraded" from a cat 10 to an 8. So to get a veranda you would have to be upgraded from a cat 10 to a cat 6 ( big jump)
We had 5520 this Jan. Awesome "free upgrade" the view is barely obstructed we loved it.
