I was interested in reserving the upper pavillion on June 16 2018 from 2-5 for my grand daughters open house. Would this be possible?

It shouldn't be a problem. Contact Gary Coxon, or Vince Parlongo for approval.

You would have to contact the park itself. Typically other users answer questions here.

Yes, contact park

This is an open forum, please call them.

Yes I see no problems if you call.
