Went here with a bunch of my younger cousins! It was really packed being a weekend, however it added to the excitement for the kids. They loved it - lots of activities to do. Lots of trampolines, foam pits, wall runners and basketball rings.
I got tired within 10minutes of jumping around. It got really stuffy inside and I felt really sweaty. Despite my personal uncomfortable experience, the kids loved jumping around and begged me to take them again the following week. We now go every few months.
I would recommend going towards closing when it is less packed. They have really late closing hours which is convenient when you want to go somewhere outside the normal trading hours.
