You can see them from the beach at POLY. I don’t know about the other monorail resorts.
This may sound dumb, but how about earplugs? I never needed them for my kids, so I don’t know how well they would work.
If you are staying at POP, I understand you can see the fireworks from EPCOT from some of the buildings. 50’s I think.
Sorry, I seem to be grasping at straws, but maybe someone will jump into with a better solution.
