If the location for the seasonal attraction is on land that you own where you will have strangers attend, you should contact your insurance agent who placed insurance on your property (assuming you have a liability policy in place) to place a binder for the type of event you wish to host for the stated time period for additional insurance coverage for liability purposes. You will have to pay an additional amount for this extra coverage.If the property where the event you are hosting is not you own and you have an insurance policy for your property, you can get an additional extension of coverage for this event. If you do not have a liability insurance policy in effect, you need to get one for the event.You will also need written releases signed by all attending the event as well as warning signs and adequate lighting.Good luck.
