re: sandwiches--my DS and his GF got to go sandwiches, I think from the beach club; i'll check.
As of yesterday 8/19 the hotel was at nearly 100% capacity. We had a major reservation screw-up and it took some string-pulling by a friend with some pull to get the connecting rooms which were supposed to be reserved. We ended up with garden view at the very end of the wing, and were assured we were lucky to get even those.
I don't know if inventory will be less by wednesday, but I wouldn't hold your breath for the upgrade. We got here around 6 and really wished we had arrived several hours earlier.
