We had 1262 (unless they have changed #ing in the remodel), which faced the parking lot - nearly dead center in the building. To the left was the back of the Boardwalk, to the right MGM. To the left in the distance we could see the Epcot ball. I never watched or looked for fireworks from that side, however, DS, went down to the 11th floor and out the end of the hallway to a small balcony area and he could see some of the Epcot fireworks from there. I was scared of getting locked out there, but at the time he went out it was not locked - you could get back in.
I'm not sure about an upgrade when you are already club level? Possibly the view would be one - maybe the view I referred to rather than a view of the Dolphin? No balconies on 12th floor to my knowledge. Or possibly an oversized room?
Anyone help me out here?
