We visited it during long weekend-group of 4+. Was pretty busy. Kids had a lot of fun (8-9y old). There is extra charge per person but it is worth it if voucher is bought discounted and used for a group of 4+. I recommend the mini golf and ghost tunnel. They're in the 2nd location-20 min walk. It's less busy there and we loved it!
Lots of kids rides. No lines to wait. Staff was very friendly and safety conscience. The shows were very fun to watch. A fair amount of rides for adults also. Great value for your money. We stayed the whole day there!
