First Floor - you get a little patio you can walk right out onto, just watch out for the ducks!! They will come right in if you leave your door open. 3rd floors do not have a full balcony - just a metal railing to look out of.
We loved our first floor wing room - although you may hear noise above you - we were wondering what kind of parent allows the kids to jump on the floor at 11 at night, until we finally realized we were right under the 2nd floor laundry room. It wasn't loud, just a mild thump occasionally.
The stairs and elevator to the 3rd floor are small - so that may be a factor. We had a 2nd floor room last trip - We usually took the stairs, as there was often a wait for the elevator - my girls liked to race the elevator to see who got there first.
