A courtyard view is preferable and the higher up the better - floor 5-7 would be best. We were on the 5th floor with a nice courtyard view and we could watch the electic light parade each night plus watch the geyser do it's thing.
The growth of the trees has pretty much blocked out any views of MK, but some people have commented that they can watch the fireworks over MK from their balcony at WL. My quess would be that since you are so far away from MK, that the "wow" factor of watching the fireworks from your balcony maybe pretty low, plus you would most likely have no other view from your balcony other than ....trees !!!
