I booked a room for 1 night at the Palazzo. When I checked in, and when I checked out I gave them my priority club number but it never registered. After a few days I emailed Priority Club and then added 2000 points for my night - I replied saying that was great but it hadn't triggered my Ambassador accelerator nor any of the additional points I had registered for as she had put it as a service extra, not a night stay. This was quickly rectified and I got my additional points and it counted towards my accelerator.
I did not get any upgrades, in fact my Ambassador status was not recognized at all although I did get the resort fee waived as I spent a total of 10 hours in the hotel!
Great room - the most basic which was huge! I would stay here again, but just be prepared to check what points get added and chase up if you think they are incorrect. I could also 'double dip' on my Grazie points too.
