For sure you have to reserve, especially if you want the electricity. I am assuming that there is a fee. Make sure to call about a week or so ahead of time to make sure you get a spot!
You're likely going to need to either call or get on the website. Especially for graduation,you'll need to check if the date you want is open. The sooner the better chance of getting one. But you will have to put down a deposit and possibly the rental fee to reserve it. Congratulations on graduating,early.
