I am very happy by this enhancement, as it will be great to have a sort of "trump card" for certain stays when an upgrade is extremely important to me.

That said the T&Cs of this are very unclear, and since a lot is being left up to the properties, I expect there to be many inconsistencies. Here are few specific questions/concerns:

- Do these certificates confirm into any (non-specialty) suite available for revenue purchase at the time, or does it come from a separate pool of "upgrade available rooms" similar to airline awards

- How will priority be determined when multiple PLTs have requested an upgrade at the 5 day mark? Is it according to the SPG rankings as suites are currently done, or the date the upgrade was requested.

- The terms are very unclear on what room type you can be confirmed into. I think it would be better if they only confirmed into something above a junior suite. I would hate to waste these certs for a "premium room" or small one room "suite". Hopefully the properties will understand their intended use and use them for something about the upgrade a PLT would normally get.
