Not much you can do when there are no available cabins on tjr ship in smy category let stone finding 2 together.
Tje one thing I have learned is that while Roydl will mskf changes that impact a guest they will not then impact another guest to make the first ones life easier.
This same situation happened to a group of my vlients with about 15 cabins impacted. Luckily we were 6 moths before final and there was lots of cabins available and I was able to get everyone upgraded to side by side and connecting balconies but fometimes there is nothing that van be gone, I'd still be asking for a bunch of OBC though.
