I feel like I know the answer to this one, but I couldn't find this precise question answered elsewhere. My wife has two expiring suite upgrade certs that she got from applying for the Hyatt card as a Platinum; we have a couple of stays later in the year that we could theoretically use them on, but we'd like the reservations to be made from my GP account (because I'm thinking of going for Diamond again this year, and because they will be reimbursable from my work). Is there any chance of doing this? I know they're not transferable, but we will both be staying.
