We were in 50's building 3 4th floor last year, facing the bowling pin pool. Looking forward we could see Wishes. If we moved to the lake side of the building we could see Illuminations. Not sure about Fantasmic but you could see the Tower of Terror from the back as well. It was pretty cool seeing both fireworks one after the other but they are off in the distance. Personally I'd ask for building 3 lake side, as we had a lot of pool noise even in January on the 4th floor.
