This is essentially like buying an rv parking spot on the lakeside in a campground, at any time of year no matter how busy it is, you can turn up.and your spot and your shit is right there. Taking my family to the beach would be a whole lot less of a ball ache if I knew I had my spot, with the buckets and spades and frisbees and towels and shit already there. Somewhere to sit and get out of the sun, no taking giant umbrellas or folding gazebos and stuff. Turn up, open the doors, open the cooler... enjoy the day.
If I were moderately wealthy this would be a nice thing to have.
