I'm starting a new thread to see if others have had the same problem, in this case with the Boscolo Venezia. I have now called Chase Premier Card Services twice about why I was not given 5 times the point for staying at a Marriott. Yesterday I was told she was fixing the correct number of points then. She had tracked down the date, the hotel, and the amount.
But why is the Autograph Collection Hotel Boscolo billing as the Grand Hotel dei Dogi? Are other recent AC hotels using their old names? It's hard to blame Chase, though it's now been two calls.
