My concern is not how the cat mapping will be done by Marriott, but whether or not one can even redeem the TP at desired aspirational property due to limited availability.
May someone that has experience with TP booking share some data points? How easy/difficult was it to redeem at 7 night award TP at an aspirational property?
I've only redeemed a Marriott award night once (SPG side), and I had a lot of difficulty finding any "nice" hotel that offered 3 nights award stay.
