Is there any way that I can host an event here? If I can, how would I go about doing that and how much would it cost?

Call and speak with an event coordinator.

Call them and speak to the event coordinator

Contact management by their website or by phone to determine availability and cost.

Go to their website and click on 'Rental Information' on the top banner

They do have special events, but you need to call them and speak to their staff.
