Tagging on to this existing thread to ask a question that I think is similar -- didn't want to start a new thread.
It looks like I will be making plat this year, with 50 nights, for the first time. I have some existing reservations that have been gifted to me by another using points or C&P.
It appears that I will not be able to use my suite night awards on these reservations, since, presumably, the primary on the reservation is not me. I just confirmed this in the Suite Nights thread with William, but I had another question that doesn't belong in that thread. How about platinum amenities for me? For example, by brother in law makes a C&P reservation for me. I show up and make sure that my SPG number is on the reservation so that I get stay credit, and incidentals on the reservation get points to my account. Will I also get platinum benefits, like potential upgrade, breakfast, etc.?
