If you are not a member you must use the Full Slot for whatever tunnel you want to book. You can only book in 30 minute increments. We have three different tunnels or you can book the whole facility for a large group. A Member Slot can only be used by members. Once you are registered you can book a time to visit the facility and instructions will be emailed to you prior to your visit.
