I have watched the fireworks from Astro Orbiter - the only caution I would give is that if you get motion sickness you might want something that doesn't revolve quite so quickly. You do have to constantly move your head if your wanting to watch the fireworks and it can be a little disorienting (especially with a little kid "driving" you. It was a walk-on/no need to disembark ride during the fireworks though so you can potentially see the whole show from there.
