My Dh and I are going to Vegas next month. We currently have a room at the Bellagio that I booked 2 months ago with a special for $104/nt. Now I regret not getting the Fountain View, but when I called to see about upgrading they said it would be $269/nt. I did not take it. I've been reading about people who get upgraded at check-in, but I've never had that experience. What do you think my chances are if I ask for an upgrade?
