I would interpret this as you can't upgrade in advance using points for a suite or higher category room, but from past posts, you are entitled to full platinum or gold benefits on award stays, and this is an award stay, so you should have full platinum benefits at checkin...if an upgrade is available, you should be entitled to it. Please confirm or correct this William. Thanks.</font>
I am under the impression that you cannot upgrade in advance. You can request.
I only understand you can get the best room available in the UG list at the time of checkin.
