Ok, so called and spoke to celebrity after receiving an email from them advising of the changes.
Was speaking with an agent who advised no changes to sailing even after I read out the email I had received. Just after that the line was cut off.
Called back and was on the phone for 45 minutes, Finally it is all sorted and our booking has been transferred over.
Whilst I was on the phone I asked the very helpful agent how much would it cost for us to upgrade our booking to a veranda from an oceanview, She advised it would cost over £6,500.
I politely declined the upgrade. That surely has to be a mistake? £6,500 on top of what we have paid for the oceanview, I couldnt believe it.
