OP here again! I'll answer as many of the questions you have posted as I can.
Yes, there is a washer and dryer, in a closet in the hall between the entry door and the kitchen.
I am in what they referred to as a "ring room" at the front desk, which I assume is the term they are using to refer to the rooms on the outside of the circle. I'm near the end of the hall on the marina side. With the curve of the building, you really don't notice any other balconies, even standing at the railing. When they told me I was on the eighth floor, I asked if they had anything facing the same way on a higher floor, but they had already pre-assigned them. I know they didn't have all the rooms taken though, because I ran into someone who was in line this morning, who told me their first MK view room was on the third floor, and not much of a MK view (we joked that it must be the Utilidor view) and they were able to move up a few floors. The view from the eighth floor is very good, and I'll have a perfect view of the EWP. I think anything from about the fifth floor up would give you a decent view (by the way, the sky bridge access is on the 5th floor), and personally I would prefer to be on the outside of the curve. There are windows every so often in the hallway that show what the pool courtyard area view would be like, and it wouldn't be my cup of tea.
I thought of another question that was asked before opening - how the rooms are numbered. Floors 1 through 9 start with a 7, then the floor number, then the room number on the floor. So if you had room 7402, you would be on the fourth floor in room two. The tenth floor and up start with the number 8 and follow the same pattern. The map they gave us is very generic and doesn't show where any of the rooms are actually located - just a list of what room numbers are on which floor.
I'm afraid I'm using a dial up connection on a very old laptop, so I can't post any pictures from here - hopefully a DVC member with complimentary high speed will be able to post some. I'll keep checking back every so often and answer questions as I can.
