WILLIAMSBURG, Va. (WAVY) — Guests at Busch Gardens Williamsburg won’t be able to bring in bags after 4 p.m. starting Friday, Sept. 24.

The new policy runs through Halloween for the park’s Howl-O-Scream festivities.

Busch Gardens says it’s an extra security measure to “expedite the security screening process and provide enhanced safety measures for all guests.” Metal detectors are already in use at the park.

However wristlets and small packs measuring less than 8 inches by 5 inches will be permitted and are subject to security checks.

Guests who bring in a bag before 4 p.m. will be able to keep their bag through the remainder of the day.

Busch Gardens says exceptions will be made for diaper bags and medically necessary items.
