@Ricardo1657 People are ______, especially when on vacation.
If the Park has a brochure or website that has a listing of visitor rules, send that information to the guest prior to arrival, and have copies posted or available on your coffee table. This does not mean that the guest will read any of it, but you will have made it available.
I would remove all firepits with the exception of a patio based firepit table.
We also have fire pits. During certain times of the year, the Fire Marshall will declare a burn ban. When this occurs, I leave a table top sign in the property stating that a burn ban is in effect and the URL of the Fire Marshall website. Intelligent guests have complied.
