Most preferred view studios will be around the pools or the canal to Hollywood Studios, so possible firework view would be the Fantasmic show at the Studios. Seeing fireworks from MK or Epcot usually requires a Boardwalk view room although there might be some Epcot fireworks viewable from preferred view studios overlooking the Village Green. Some of the upper floor resort view (former standard view) rooms might have a view of the higher Epcot fireworks. Since the laundry facilities are on the ground floor near the elevator lobby, rooms near the elevators are the best option. The rooms overlooking the Village Green are reasonably near the elevators. Unfortunately, those rooms are relatively few in number. Some rooms overlooking the Luna Park pool might also be nearer to the elevators but these may not be great in terms of viewing Fantasmic fireworks because of landscaping and other parts of the building blocking views.
