I stayed over the weekend using one paid night and one free night cert. We were upgraded from a standard king room to a deluxe king room on the 45th floor and our welcome gift was a basket of fruit and a box of chocolates. However, we encountered a lot of similar issues to the previous poster.

* The hotel didn't link my two reservations despite calling ahead and asking them to
* Even after checking in, the receptionist told me that I'd have to visit the front desk the following day to receive new a new room card. When I questioned why, he appeared to have made a change.
* Upon returning to the hotel Saturday afternoon, the room card had still been deactivated. More frustratingly, after getting a new card, we discovered that that the room had not been serviced. I called housekeeping and asked if they could do a quick service while we went to the pool for an hour, but it still wasn't done when we returned.
* There didn't appear to be an Ambassador check-in area
* They crowds were pretty massive, and worse on Friday evening than Saturday, presumably due to post-work crowds
* After requesting a 4pm check-out, I was told that 2pm was the latest check-out I could get. After referencing my Welcome Letter with 4pm checkout as a listed Ambassador benefits, my request was approved.
