All three of the resort properties offer fireworks views from certain rooms. The PPH has viewing on its pool deck and pipes in the music and the concierge lounges of these hotels do the same thing.
Just about every off-site hotel directly across the street on Harbor will have some kind of view of the fireworks from certain rooms. The above poster is right that the HoJo park view rooms have views from the balconies, and you can also see the fireworks quite well from the pool/jacuzzi area.
