4/5 - Good
We got there when it opened and literally had some rooms all to ourselves. It did start to pick up mid-day, but was manageable. All of my kids had a great time. While geared towards the younger crowd, my 14 and 11 year old had so much fun exploring with their 4 year old brothers. My sons especially loved the room with the water... they could have spent the day just in that room!
