we went last year with kids in those age ranges. my oldest boys were 10 and daughter 8. (we also went 3 years ago as well.) imho it is a great event worth the extra $$ for all ages. Fireworks, parade, and shows are great. first year we went just the kids dressed up but last year hubby and I joined them. My only advice is that if you plan to eat at the parks do it earlier rather than later. We got there early last year as I discovered on these boards that you could get in earlier than the ticket stated (I think it was 4) and instead of eating first we hit a couple rides. We were frustrated when we realized where we had planned to eat was closed. Not all eateries stay open for the party. My kids and I are picky eaters so it was a big deal for us but probably not for most families!!!! But something worth noting just the same. It is still a great night!!!!
