Designated bike trails are nice if you have the property. The longer the better. Helps kids burn energy, keeps them off the roads and your walking trail and gives them something else to do. Doesn't have to be paved so it's relatively inexpensive to add. A mountain bike trail or cross country trail would be a plus if the terrain allows.
Not sure whats popular in your area. shuffleboard, horseshoes and even cornhole I've seen more recently. Mike
I'm a new workamper/park manager in Utah and I did some research on what RV people are looking for. This is the most asked for: large and level pull through sites paved or gravel with shade/tree/bushes/awning/fence between them. Full hook up, great WiFi, a dog park, clean restrooms, shower & laundry room. Private showers. The park I'm in opened in June and the builder/owner faced all the issues in post #3 and he's still having problems. I was researching if small RV parks have soda vending machines when I ran across this thread. I'll continue to follow and hope to gain information to help this owner.
