The "comp. upgrade (based on availability)" benefit is stackable with the room/suite upgrade certs.
E.g.
book Fairmont room
-> use room upgrade cert to upgrade to a Deluxe room
-> you may get an upgrade to the next room category (e.g. Signature room) at check-in
or
book Fairmont room
-> use suite upgrade cert to upgrade to a Junior Suite
-> you may get an upgrade to a one-bedroom suite at check-in
Thanks, how I thought it would work. I know who to contact when I will want to try it out
