★★★★★Joe TrecokasHad a great time for a 7th birthday party at the Royalton location. Grace was interactive with the kids. Clean facilities. Would recommend this for sure. We’ll be back for evening fun.
★★★★★Rita HeerWe had our daughter's 7th birthday party here and it was amazing! The owner was so kind and helpful. Elijah helped as the instructor for the course. We had a few little kids with us so Elijah made sure they even had activities to do. We will absolutely book again in the future and appreciate the warm hospitality that the staff showed us! Thank you XNW team!
★Kali ShockleyDo not recommend this place. We attended a party & they didn’t even know there was a party. (But mind you our party was on the website for kids to sign waivers) They then put everyone in what looked like a storage room with a few tables. It was an absolute free for all with kids. There were not even any parents there watching their kids. We had a lot of kids come into our “room” taking food and cake. Parents were literally up the stairs at the bar. Couldn’t tell who was staff and who wasn’t nor was staff even paying attention to what was going on. The owner was absolutely terrible and rude. Another parent went to tell him something and his response was “you need to wait, I’m doing something” and then said “I don’t care that’s not my job to stock bathrooms, you need to just deal with it” They willing and happily took our friends money to pay for the not cheap event. But if you ask me they deserve a full refund for the experience they had. Never again.
★★★★★Megan GuthrieWe celebrated my son’s birthday here with a group of 15 of his friends, they had a blast playing on the equipment and the coach, organizing the games. We’ve even had our own private party room for a birthday cake and snacks and present opening. Great experience, highly recommend!
★★★★★Joy Fenton-JonesWe have started our almost 2 year old in Ninja 1. Coach Sam is beyond patient! We're really grateful for a spot that is so flexible and great with little ones!
