Given that Plat is not even the highest IHG Rewards status any longer (you can pretty much get it with signing up for the IHG credit card in the US) for IC stays only Royal Ambassador or Ambassador give any committed benefits. I would say of your desired list of potential benefits / goodies at the IC TS maybe an upgraded room (higher floor / better view) could be possible, but not a sure thing. In the IC status guest "pecking order" (and ignoring actual VIPs or so) your status will feature only after RA, AMB and Spire.

Possibly a non-IC hotel may treat you a bit better (I never stayed at the CP TS) as RA or AMB don't matter there so after Spire your Platinum status would be the highest (and some hotel staff still think Platinum is actually top tier). If you decide to stay at the IC TS expect to receive what you booked and you won't be disappointed. YMMV.

Ohh and book the IC TS before Feb 17, 2016 or it will cost you 60K per night versus 50K right now.
