If you would like to rent the large pavilion the current price is $160. You can make reservations online at the city website in parks and recreation tab under the pavilion rental section. If you would just like to set up May tent on the grass, it is first come first served.
For the most part it is first come first serve. As far as I know only the pavilion can be reserved for a small fee. Access online via the city's website, look for the parks and rec team then down to the pavilion rental section. I believe it is around $150 or $170, or it was last year.
You can have birthday parties in the gazebos. It is first come first served.
