Nothing yet on mine. I keep checking the reservation page just to make sure it's still there. They cancelled a reservation to another con on me and never informed me. When I made the reservation I did it with a card that was cancelled due to suspicious activity and they never contacted me so when I arrived I had no room. Fortunately the Hotel was good enough to honor the original reservation so I was fine but it could have turned out a lot worse. It doesn't hurt to double check those reservations!
