Frequently Asked Questions

What happens if rain washes out a family event we booked in Arnold?

Read the policy before buying: farms usually offer rain checks for another day that season rather than refunds, while ticketed indoor events run regardless. Light drizzle often means a gloriously empty farm, so don't auto-cancel. Keep one indoor backup, a museum day, library event, or home carving afternoon, planned for each outdoor weekend so the costume doesn't go to waste.

What are the best costume choices for kids attending outdoor Halloween events in Arnold?

Pick costumes that survive walking, climbing hay bales, and a bathroom trip in under two minutes: no floor-length hems, no masks that block vision, and nothing that can't fit a jacket underneath. Sneakers always beat costume shoes. Add reflective tape for evening events, and pack a backup shirt because face paint, snow cones, and petting zoos will find white fabric.

What hygiene plan makes petting zoos at Arnold farms less risky?

The rule: animals, then handwash, then food, in that exact order, every time. Use the farm's wash stations rather than sanitizer alone when hands touch animals or fences, keep pacifiers and sippy cups in the bag near animals, and don't let kids eat inside the enclosure. Strollers stay outside pens. It's two minutes of routine that prevents the classic post-farm stomach bug.
