Just left HNS. Kids are tired and happy. Wide variety of games and experiences. Bright and clean. Decent use of tech interacting with physical activities. Trampolines don't feel like death traps. Good, natural barriers for younger/less able kids. Air pressure ball games are unique and enjoyable.
One draw back is the open design and the weird/boring dead ends that it causes. Don't care for the pay games, but I'm sure it's fine for those who like that kind of thing.
Staff is friendly and constantly cleaning. Coffee not atrocious.
