I just got my Diamond upgrade.
I had considered using it on the Dawn cruise which we just booked for this September, booking an Oceanview and upgrading to a balcony, but was too nervous about getting allocated a bad room, so in the end we went for the Viva, upgrading from a balcony to a club suite. I don’t see any club suites as being in too bad a location.
As we are in the UK, I decided to try emailing rather than calling. I rather cheekily asked for a front corner room, which are a few hundred pounds per person extra.
I just got the reply today, three days after emailing. Unsurprisingly I didn’t get the corner room. We got a room in the aft block on deck 9. I would have preferred 10 or 11, to avoid being directly above the dining area, but I’m happy with 9 as we won’t be in the room much when the dining is busy.
Not ideal, but I’m happy enough.
The cruise is in two years time, so that is more confirmation that the one year restriction is in arranging the upgrade, not taking the cruise.
