Booking THC room for an additional card member

Here’s my situation, if I book and prepay for a THC room with my platinum card for my spouse, but then my spouse checks in and not myself, will she still get all the THC benefits? My spouse is an additional card member (the white card) and not an authorized user (or maybe it’s the other way around - whichever one is free is the one we have). I also want to make sure I get the THC credit (NOT an extra one, I get that).
