.Extremely disappointing experience. We picked our room and did our initial check in through the Hilton app, it only gave us 2 room choices, one in the Riverside Building and one in the Tower building. We chose the Riverside Room, however upon arrival it smelled like cigarette smoke, not wanting to be blamed and charged for this ($300?), my husband went to the desk to report the smell and get our actual keys. The front desk offered to upgrade us, big mistake! The 2nd room was anything but an upgrade, the air conditioning didn't work nor did the refrigerator. Also our view of the river was blocked by the dinner ship. But even forgiving all of that, the worst was yet to come. Our 2nd day there, I had the DO NOT DISTURB sign on the door. First housekeeping came in while I was getting in the shower, she them came back a 2nd time to question whether we were okay with her room cleaning, then for a 3rd time the housekeeping supervisor knocked on the door to see if we had extended our reservation????? We were still on our initial reservation. I have never stayed in a hotel where the staff came in when you clearly asked for privacy. Also we are Diamond Members and should have received 2 cards each day for $10.00 off hotel restaurants or stores, we were not even informed of this until we were leaving. Then when we received our bill at checkout it was in someone else's name, on their credit card. This could have and should have been an amazing business trip at an awesome hotel, however due to employee issues and extreme hotel confusion it ranks right up there for the worst stay ever. Be careful, be vigilant and make sure the hotel treats you with respect and actually cares that you are there. They will not do it without your persistence and even then your stay will not be what it should be.
