That is very true, but the hotel when assigning the upgrades which in my case has always been done in advance, may be in the position as I described in my previous post. Just because the T&C doesn't spell it out doesn't mean they don't use rate paid as a determining factor in assigning upgrades when there are less upgrade rooms available than the number of Plats checking in. As far as that is concerned the the T&C provides no guidance in this regard so my guess is that any hotel can use any method they see fit including rate paid.

On Tuesday March 16 my Hong Kong Renaissance reservation for the 17th showed Exec Level room. My Ren CC here in London which started on the 18th showed Club Level room online on the 17th. And my reservation at Dubai JW for tomorrow now shows Exec Level room whereas it did not a mere 5 hours ago. Now I don't know how RIs assign their upgrades, but if it is anything like FS properties then they do it in advance.
