There is one work around that can get you additional stays, without leaving the property. But, there are a few limitations.

The main limitation is that you must be sharing a room with someone.

With that, you can check in one night under your name. The next night is booked under your fellow guest's name - yes, you will have to change ROOMS. The third night you check back in under your name. Oh, and change ROOMS.

So, on a 3 or 4 night stay, there is the opportunity to get 2 stay credits. Not as good as 4 stay credits, but better than 1!

Disclaimer : I did this a LONG time ago, during a promotion that required stays. I earn Platinum based on nights.
