The best part was the guide's narrative along with the sights.
Awesome trip! Not too long for the little ones but still great for everyone. Our guide, Andy, was very knoledgeable and funny as well. I highly recommend this. Gets crowded so this deal is awesome. Get there 45 minutes early and grab your ticket, you can then walk around and wait.
Really good and is cheaper in viator from buying them from the desk there.
