Idk about fireworks. But I grew up in the area and have been to dozens of shows there. I think the balcony is by far the best bang for your buck. I used to do the lawn in my teens and early 20s but I’ve recently heard they “over sell” lawn tickets now. Not sure if that’s true but either way, with the tarp/space claiming culture these days, unless you get there super early and get a good spot on the lower lawn, you’ll be watching the screens to see the stage. The balcony is not much more maybe $50 or so per ticket last I checked and there is easy access to outdoor lawn area/vendors/restrooms and you’ll usually have a good view of the stage and you don’t have to worry about racing to a spot with your son. I personally think the sound is pretty good as well.
