In no way shape or form am I trying to get you to not go to the show ( I've only been once when i was 7 or 8 yrs old so it has been about 13 years) but if you decided not to go then i would look into 'Ohana's. The food is wonderful (all you can eat steak, pork, chicken, or shrimp) and if you get priority seating around 6:30 and ask for a back window seat then you will be able to see the fireworks at the MK that start at 7:00. During the fireworks they will dim the lights and pipe the music in from the fireworks show.
Once again, i'm not saying that you shouldn't go to the "Spirit of Aloha" show but i'm just trying to give you an extra option.
