Minnie - I am not positive, but I do not think that all 5th floor concierge rooms have full balconies.
For concierge check-in you do not go to the Front desk or curbside. When you arrive at the resort, you tell the doorman or bellcaptain that you are a concierge guest. The concierge staff from IPO (Itinerary Planning Office) should send you in the mail, a plastic card that you use in the elevator to go directly to the 5th floor. You actually check-in with the 5th floor concierge staff.
Not sure about the views. As you see from my counter, we are only going for our first Disney trip this August. But since we are going concierge, I have been working with the awesome IPO staff, and I have learned quite a bit.
Wow 4 tags! The tag fairy must really like you.
