Farm food is fun but slow and pricey at peak: cider donuts and one treat as the event, real meals before or after. Lines shortest before 11:30 am. Bring water bottles and a backup protein snack per kid, and check payment types, since some stands are cash-only while others are card-only. Picnic tables fill by noon, so scout your base early.
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.
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.
