What are some tips you can share for autism and halloween?

I am sure there are many out there who would love some good tips for Halloween, game ideas, and help with some sensory issues that come up. My son loves to dress up for Halloween and go trick or treating.

For some it can be a tough a time. What do you do for meltdowns, and overstimulation, or sensitivities to certain foods? Please share it will help everyone.

Twitter them as well. I haven't seen many posting enough about this.
