Everything was easy from booking to party clean up.

We just had my son’s 5th birthday party at Bladium.  He chose to have a Lil’ Kickers party.  He and his friends had a blast!  Everything was easy from booking to party clean up.  The hosts were amazing; high energy and very helpful!

Our party host, Jess, was great!

We had my sons 3rd birthday party at Bladium. We did the Inflatable Fun Zone Party with all the bounce houses. It was better than we expected! There are so many huge bounce houses. The kids can choose between different size slides and houses, different types of bouncers, all different ages can play. … Our party host, Jess, was great! Such a spunky and fun attitude, super helpful and assisted us with all our questions and needs.

The kids loved it…

…When we arrived parking was easy and the place was easy to be found. The place looks huge from the outside so it wasn’t hard to miss. Walked in and was greeted by the staff and they guided us to the party location. The facility was big, I even saw a basket ball area. The area for the nerf gun party was huge as well and even had a blow up obstacle court. There were plenty of still objects to hide behind and the ground was fake grass so it was safe to roll around and take cover. The kids loved it, they had so much ammunition laying around so there was never an issue of the Kids running out…

…the “bouncy house place”.

My 4 year old nephew calls this the “bouncy house place”.  This is where my sister decided to have his birthday party a couple of weeks ago.  It was a great spot for a bunch of 4 year olds to run around and play for a couple of hours…
