I'm not a Plat anymore and haven't had the need/opportunity to change the Promo assigned to me. From the posts I have read here in the past, it seems most were actually getting their Promo's changed. I haven't heard anyone talk about the need for a manual entry here.

What I would do is call the Rewards Help Desk and see if you can find out the exact breakout of those "extra" points you received from your last stay. I'm wondering if they aren't from something else. It sounds to me as if you were never changed to the 35K promo. And if that is the case, you may have to fall to the mercy of the Help Desk on getting your extra 10K.
