Wheelchairs and Electric Convenience Vehicles (ECVs) are available
for rent. The rental booth is located inside the park just past the
turnstiles. A limited number of reservations are taken by calling
1-800-475-9370. Reservations must be made at least 24 hours in
advance of your visit.
All guests using ECVs must follow park rules, the manufacturers
guidelines and instructions given to the guest during the rental
transaction. Only one guest per ECV or wheelchair is permitted.
Guests between 16 and 18 years of age must have a parent/legal
guardian at least 21 years of age sign the rental agreement.
Please Note: Due to the terrain of the park, guests using these
devices shall follow the designated pathways outlined in the
park map and instructions given at the time of rental. Leaving the
designated pathways may cause the ECV/Wheelchair to become
unstable.
