Great review! I was aware of the renos - but - I did not know how stingy they are with Plat upgrades.
BTW, while you were in house, the hotel was hosting hockey players participating in a big midget hockey tournament. Might explain the elevators?
You are 100 % correct about the Sheraton. I had a $89 stay last Dec to complete my 25 night min. While the lounge was closed but the full buffet brekkie was nice!
