🎃 Designate a meetup spot — cell service gets spotty in big festival crowds.
🎃 Arrive before noon — parking and popular food lines get rough by mid-afternoon.
🎃 Bring cash and card — some vendors are cash-only, others card-only; cover both.
🎃 Check the schedule — headliners, costume contests, and parades-within-the-festival have set times.
