Good luck with that. There is no handicapped viewing area like they have for the parades or Illuminations. We used to try for the bridge to Tomorrowland or close to the rose garden, but the rose garden area is now taken for those with FPs. The bridge fills up really fast. Anywhere else, all you see is everyone's butts who are standing in front of you. You could always pay for ADRs at the Dessert party. I've about given up trying to find a spot where I can see from my chair. So we just find a spot behind the castle. You can't see the castle displays from there, but I can still see the fireworks and hear the music. No crowds.
