Are there pickleball courts here?

Yes, they are painted next to handball courts at NW corner of the park.

Hi, what can I do about someone who put tables at the handball area since 7:30am until 2pm to reserve his spot to play pickball ? he refuse to play at the painted pickball area and doesnt let anyone get into handball court. A few people tried to speak with him but he refuse to leave, he comes there daily and also get paid for classes.

No

Yeap
