I searched for the problem and saw that more people had this problem. I discovered something with F12. When you enter the hotel and the guy in white sits at the bar and the ketchup is not active. Click on the drunk guest in white on the bar and right after you start walking towards him press F12, he disappears and you go stand before him. Then notice that your cursor still says guest in thin air, click on guest and now press F12 again. It triggers a conversation from the night before. Just click through this and you walk to the door. Now the ketchup is active!
See if it works.
