Most golds/diamonds stay at other properties in London (because the Green Park Hotel doesn't have a lounge), so you will get upgraded if rooms are available (not sure about the suite... when we were there, the hotel was half empty so they certainly had pleanty of open rooms. We also let them know we were celebrating a special occasion, that might have been the reason for the suite upgrade, along with the free drinks at check-in and the half bottle of wine waiting for us in the room).

To answer your question they do seem to be good about room upgrades if they have available rooms. The location is great btw. The green park tube is fairly close.
