Entrance to the gardens was surprisingly free, price paid for entrance to both domes was worth it especially the rain forest. Light show was like nothing we had ever seen before, totally amazing. Best time to go is mid afternoon, then you have time to walk all of the magnificent park and find a good spot to view the light show. You can take a picnic and sit on the lawn to watch the show, and as its free you can do this every night if you want to!!!
