Avoid room 5530. The balcony railing is solid wood, when you are standing you are fine, but when you sit down it is like you are in a box - you can't see a thing. It has something to do with the roof line. We noticed this as soon as we got to our room and called gs, they said we could change to a first floor room. We decided not to go, the hassel of moving, get new room cards, etc - we had waited for our room a long time as we had arrived around 1 and could not get in till 3. Of course as the week went on we wished we had taking the extra time and switched rooms. We also were not crazy about a first floor room - although our opinion of that changed as the week went on. I know there are other rooms with the same balcony set-up, so you should check as soon as you get in the room.
Also don't forget to sign-up to be the flag family - it was great!
