I hadn't been to the Circus since I was a little kid... and that was in an actual circus tent. I took my 4 yr old daughter and she loved it. We had club seats in section #319 of the Honda Center. These seats were basically to the right of center ice/center court. We had a great view of the entire circus floor, especially the high wire acts. Ticket prices were only $25.00 (plus all the additional fees).
Pros: lots of things going on the floor to keep my 4 yr old occupied. From the adult viewpoint, it reminded me of a Cirque de Solei vegas style show except with animal and magic tricks. Also, 1hr prior to show time you can go on the floor for pre-show stuff like Elephant painting, clown show, try on clown costumes. There is a 10-15min intermission after about 1 hr into the show (bathroom break...yes).
Cons: bring lots of cash - Cotton Candy $12, Kettle Popcorn $6, Sodas $4.50/bottle, Sandwich w/ chips $9.50, Circus only once a year...priceless!
