On my past 3 reservations where I couldn't apply my SNAs on pre-paid rates, I emailed her. She replied saying she emailed the hotels and within a day, all my 3 room reservations showed as suites. No, I did not receive any fancy F&B gifts or note in the room, but I appreciated that she got the job done.

Now I have 13 more SNAs left and don't know what to do with them.
