SPG Plat-50 here...

Anyone have any luck adjusting prepaid reservations booked within the past couple hours? Trying to switch from one Starwood hotel to a different Starwood hotel a few blocks away. I feel like I've done this before but my first attempt on the phone was greeted with "very strict policy", despite my suggestion that there might be some plat-50 magic.

For what it's worth, I'm trying to switch to a hotel with a higher rate (Four Points to Westin in San Diego).

Thanks!
