Its actually on the 4th floor, opposite end of the building (Chef Mickeys is on the transportation center side). Just past the shops on either side there are 2 doors that lead out on to a balcony. You wont be able to see all of the show as the trees block the lower stuff and the images projected on the castle, but its still worthwhile. Dont forget you can also catch the water parade later on out on the beach (near the wing rooms). It comes pretty late though as it is the last stop (back in Feb it was a little after 10pm).
