We spent 5 hours here and would have spent longer if we hadn't been so hungry! The whole experience is quite interesting and unlike anything else we've experienced. We got there in the morning (around 11am) and it wasn't super crowded (we had to wait for 1 group to go in before we got to go in) but definitely was a lot more crowded by the time we left so I suggest going early (we went on a Sunday). There is no map so you don't know if you've missed anything. I was bummed because on our way out we found something we had missed doing but the line was so long, we had to skip it. My kid is 10 and would have spent the whole day here.
