We are going but this is because our chapter does the 1 special extra thing and this was ours. My son has never actually been trick or treating so this is why we wanted it for him. Gavin in mentally disabled and when we have tried to do the door to door thing or even trunk or treating he wanted to go and explore. It would make him mad when we would go to doors and then just leave. This doesnt make sense to him and if you think about it the whole concept is kind of is crazy if you look at it from his concrete perspective We are excited because I think this will be the perfect thing for him. We are also excited at all of the extra character visits. However, I think in your situation there is no way that I would pay that much money and possibly put my son through some extra stress. If you think he might just like the characters you could check out the Spooktacular at Sea World on Fridays. It is free with admission and I read that they have some special things going on. I hope this helps and I am sure whatever you decide you will have a great time.
Thanks for your input - the more I think about it, the more I think it would just be a bad idea for him.
