I would book the room you want and not count on this property to do anything above and beyond what they are required to do for you - if they even do that. Unless you are a returning, cash paying Glob, getting a suite (even the junior suite this property calls their standard suite) without using an upgrade instrument is unlikely.
I am a returning guest (I've stayed 3 times prior & have a loose connection with Cecile, the guest relations manager) so I was going to reach out directly to my contact once we've booked to let her know we're coming.
