For 10 of the 13 years we have had a temp location. Now that we own the location we are still using tents and change the places on the farm where we set up the "houses" and paths. Most years space has been donated to us, other years we have traded tent rentals or a percentage of the door receipts. We have had zero luck with real estate companies - zero. For the best results find out who the owner is and deal with them directly. If you can use tents, it does take some of the pressure off and opens up more possibilities.
