I start working with my voice about 1-2 months b4 season kicks off just so i have plenty of time to get my vocals in shape.
I also try to warm up each night before i go on whether thats takin a jog around the stadium or just stretching out in the locker room if im short on time.
Try to get them to cut down on junk food, tell them if they have to eat out eat subway. Junk food, pop, chips, candy, and greasy burgers and fries only hurt your energy levels and your health during the haunt. Tell them salads, fruit, and veggies are their best friends!
The best advice i can give though because badge and kate already covered most of the "get ready" stuff is to push your actors to take vitamins. It never fails i always end up in the hospital around halloween trying to battle some horrible sickness. I try to push the vitamins as much as i can but i have a weak immune system anyways.
Tell them to keep the vitamins going and keep everything at their stations sanitary, you dont want a flu bug ravaging your haunt actors and completely killing their drives. Baby wipe everything down and keep them from sharing food, drinks, and any sort of lip makeups or tooth makeups. Keep hand sanitizer handy for before the night starts and after its finished.
Keep those actors safe, fit and healthy
