Another couple of weekend stays and some more updates.
Good changes: On my last stay they had the breakfast voucher waiting for me -- no need to demand it. There was a "message" code in the computer to alert the agent to give it to me. I saw another one sitting there, so assume this is for all platinums. Hope it lasts. Also, as well as the breakfast voucher there was a $10 voucher to use for an appetizer in the restaurant (open until 10pm in the evening). That made for a nice evening snack. (As the previous poster pointed out, the dinner menu is still pretty fancy). Also the room rates just get lower and lower at the weekend.
Bad changes: More than most other Westins they are skimping on in-room ammenities. One soap, no bathrobe on the last few stays, still no shower gel. The nice Aqua Panna water seems to be gone for good.
Gripe: Two stays running had bogus charges after checkout -- one for $6, one for $23. I wrote a letter to the GM, dropped it at the front desk -- six weeks later no reply. So I'll have to send it to corporate customer services.
