We also have wood heat and have found that, no matter how many fire-starters and kindling wood we leave for guests, they use all of it. Every time.
Apparently the attitude is “I paid for it so I will either waste it or take it home.”
One guest even loaded up about $40 worth of seasoned oak and took it with them.
A box of fire cubes costs $25 and we have learned to leave no more than 2 cubes a day.
I also start the fire before guests arrive and advise them to keep it burning.
A good, inexpensive fire starter can be made by dipping a cotton makeup-remover pad in Vaseline and I believe I will supply that this winter.
Unfortunately you cannot overestimate a guest’s ignorance. We have had some who could not understand the function of the stove damper even after I demonstrated it.
Others refused to believe that the fire would keep burning with the stove door closed.
I try to warn off the terminally stupid before they book but it doesn’t always work.
