I was trying to apply my TSU to a P+C reservation but the standard suite availability for some reason disappeared while I was on the phone with the WoH concierge.
It was still available on the first 2 days of my stay though and the rep said that he's able to split my reservation into 2 parts (keeping the same confirmation number) and secure the suite on the first 2 days for now. I see that the TSU was deducted from my account and the reservation shows up as 2 "icons" in the app although the room description for both remains as standard king which I will have to call to check if there are any issues with that.
Didn't know this is possible. Curious if this i.e. getting the suite upgrade for partial of your stay is something that can be requested as standard practice?
