My family visited Ultimate Ninjas Libertyville for a birthday party. I was very impressed with the service, instruction, and attention the kids received while on the Ninja course. The birthday attendants kept close watchful tabs on the kids to ensure everyone's safety and got an ice pack for the birthday boy when he bumped his head. 40 minutes on the warped wall (several different heights), then 40 minutes on the Ninja obstacle course plus basketball and a fun game of dodgeball, and then 40 minutes in the party room. The attendants kept the kids busy on the obstacle course, were attentive and taught the kids the game of dodgeball, and were super helpful in helping with the party (carrying the cake to the table, passing out anything needed by the parents, and helped me take down decorations! I was very impressed with the service compared to other kids party places I have visited. I would hands down recommend this place for kids birthday parties! My kids loved it here! Make sure to check out the different walls throughout the facility with large photos of famous America Ninja warrior contestants and kids at the gym. Super cool place, for kids and parents alike!
