Ninja Nation - Centennial — Local services in Centennial

We had my son's birthday party here yesterday and it was fantastic. The main reason we settled on Ninja Nation was because it's the only age appropriate, high activity place that could accommodate a large group where we could still feel like we stayed together as a group. At other venues, you eat together and then everyone splits up into large play areas and you may never see some of them again. Ninja Nation is a large facility, but not so large that you lose people in your group. My son still played with all his friends and parents didn't feel like they had to follow their kids around. Most parents watched from our party area. At other venues that are more private, they can open up the play areas, but the party rooms often only hold 20-30 comfortably. At Ninja Nation they have partitions they can take down between the party areas. Jungle Quest also seemed like it would work, however, the clipping in and out of the harness was a little difficult for some kids and I think they only provide 2 helpers. I didn't want parents to feel like they had to follow the kiddos around each apparatus.

We booked Ninja Nation and were pleasantly surprised by how awesome everything went. Parents even commented on how great the party helpers were. The biggest difference to me was the fact that the employees were slightly older than at other venues we've hosted parties and more mature and attentive. Both in the arena and in the party room the staff were patient, friendly, efficient, and service oriented. They wore gloves while handling food, made sure kids hands were clean before eating, served up everything, and cleaned the party room. In the arena we noticed that they knew where the kids were likely to fail in the obstacles and were there to help and kept things fun and organized. They were so polite to all of our guests.

I've read some comments on Yelp about it being crowded. If you're going to any of these types of activity venues on a weekend, it shouldn't be a shocker that they get crowded and you will need to be more patient. I've been to Ninja Nation as a drop in customer on a weekend and didn't feel like it was any different than sky zone, jump street, spider monkey, boondocks, celebrity lanes, lil' monkey bizness, family fun center, etc.

My only negative comment is that you must order pizza through them. I prefer to go through a different caterer, but the reason I ultimately didn't mind was because the manager, Jill (who is fantastic by the way), told me it was through Parry's.....which we knew of and love. We were able to bring in a fruit/veggie tray and our own cake, so we felt a little better about it. Parents enjoyed the pizza as well; you can order any pizza ioff the Parry's menu so we didn't just have cheese/pepperoni. At the end of the day, I have to say, it was MUCH easier just having pizza taken care of by Ninja Nation, so it's hardly a negative. The set up of the party area is also better than others as they have high narrower tables for food along the wall and picnic style tables for the kids/parents to eat.

I highly recommend this facility for birthday parties and other events. Adults, teens, and my sons first grade classmates all had a terrific time on the obstacles. From a planning perspective I would be happy to use this venue again. We had positive interactions with the arena manager, front desk staff, coaches, and...

If you're hosting a winter birthday party in the Denver area for a relatively large party of kids, you know your options are somewhat limited. Ninja Nation truly does it all! This place is well-run and has their planning and logistics down to a science, really taking the stress out of the whole process. We paid to have the party host, and he was so great with our party of nearly 20 kids, showing them "the ropes" and getting them started with jumping jacks before running them through the various obstacles for over an hour. And this also allowed for all the parents to catch up and converse, which was most welcomed. And a few days before the party, we spoke to the management team to get final details hammered out like signing of waivers, activity timelines, and, the all-important matter, the food: we reviewed pizza numbers (which they handled, and was delivered in from Anthony's, which as far as local chains go, is certainly one of the better ones, I think), what drinks they would provide, and how the desserts would work (which we provided). And our host set up all the plates, cups, and food, wearing gloves and reminding the kids to wash their hands--little things like this are a massive help when corralling such a large swath of wee ones. Also, we were given a cart to transport our items from the car, including the presents back at the end of the party. Again, we really didn't have to do much else but show up and have fun. Certainly the most expensive kid's party we've had (especially when adding a well-deserved tip for our host), and a bit of a trek down for us all here in central Denver, but when you see how detail-orientated, clean, and exercise-centric this place is, it's sort of a no-brainer to have your next kid party here. Bonus: as parents of the birthday kid, you get to try out some of the course as well, and therefore really get reminded of how middle-aged and...

We've gone for several open plays here with no problem. When it comes to getting in one of their competitions we ran into issues with their current software and getting the slot booked.

Assuming there are plenty of open slots (as the screenshot would infer) I tell my son about it and get him all hyped up for it. Well, once you login to the system, still the same. Once you click through the "Sign up now" button you get to a page that tells you everything is booked up.

So, I call and tell them this expecting that they could make an exception since the software they're using is obviously not a good fit. Luckily, the owner replied and was able to move things around to get a few more open slots.

This means a lot to my son as he was very much looking forward to getting to go to this event. My fault that I got him all hyped before the bookings were finalized but needless to say I'm very pleased with the management at Ninja Nation. I understand the issues that small businesses face with technology today and these guys handled it well.

If you're looking for a great place to take the kids then look no further than Ninja Nation. Kids of all skill levels are sure to...
