The OC Fair is a great place for people of all ages. Everyday is packed with entertainment, food, games, rides, you name it! However, I strongly advise you to plan your day out FIRST. So, before you go, look up the event schedule online. See what shows or exhibits you are interested in seeing, then create a schedule that allows you to see as many of them as you can! (You may not get to see them ALL since many events run at the same time and overlap-which is good because it shows you how many options you really have!)
If you don't plan out your day ahead of time, you'll end up going there and spending all your money on games and rides and food. To play games and ride rides, you need to first buy tickets. Tickets are $20 for 40 tickets. To give you an idea of how long that'll last you....
You and your friend are at the fair....
2 tries at balloon dart game = 5 minutes, 14 tickets
2 rides on the wild mouse ride = 10 minutes, 24 tickets
15 minutes pass, and you're already down to 2 tickets! you and your friend each played one game and went on one ride, and now you're down 20 bucks.
The games and rides are money pits, but the neat exhibits are totally worth it and make the value of your ticket seem like a huge bargain. Ice sculptors, animation demos, acrobats, singing, dancing, hypnotists, barber shop quartets, petting zoo, galleries, shopping... you can even have your picture of you sitting on an elephant!
