Ideas for building the cheapest temporary pickleball court.

My kids & I are into pickleball but our local small town pickleball courts are always so crowded. I want to build a temporary court on my property. By temporary I mean one that is a pad on dirt that will hold the weight of teenagers & bounce a ball. One that is the cheapest possible & can easily be taken up & removed within 3 years. I don’t care if it it’s ugly, gets cracks or that it can’t hold a car. I was thinking of heavily adding gravel or other material to bulk some concrete up & then maybe a one inch straight concrete on top. Or possibly just adding rubber tiles on top of the bulked up concrete. Would that be something that would work for this purpose or is there a better/cheaper way?
