I guess first it would depend on if you booked with a discount like Ent or APH. If you did, you are not likely to be given an upgrade. I am assuming you have a standard bay view room, then I think it could be upgraded to a deluxe room. I had a bay view deluxe last week, wonderful room, fabulous bathroom, and view. Lastly, it would be dependent on whether they have an upgrade available at check in or not. If all the deluxes were booked, I don't think it would be possible to get an upgrade either.
