Sorry to revive an old thread, but it is relevant.
So, we're 24 days out from sailing, and I've had a bid accepted - granted it was for the least best of the three choices originally offered (premium suite aurea - the others were grand suite aurea with w/p and Y/C Deluxe Suite).
I offered what I was comfortable with paying extra for each based on what I paid for our balcony and what these would have cost at the time - overall got the upgrade for less than half of what it would have cost at time of booking, so for us, happy days!
