My son and I have only been here once and what CGRNM had to offer indoors was great and they had some displays that children can handle. It was also very reasonably priced! The ruins themselves...well, they weren't that special. When my son and I went we were not able to go inside the ruins. I'm sure since the last review was in 2009 there have been structural changes to the ruins. It mostly looks like partially melted mud huts and since you can't go inside you'll be done with that part of the tour in about fifteen minutes. I also don't recommend going in the heat of the day during summertime there is no shade anywhere out doors and it's brutal.
