  • This was our first time here. Although it was such a cool and unique experience it’s not quite worth the hefty cost. In theory what they do at this site is pretty cool and interesting but for what you pay you can do without. Our tour guide was very nice and he had some pretty cool jokes. It was extremely hot when we went and if you plan on going make sure to take your sunscreen, hat, and water bottle. They have refill stations throughout the facility. I wouldn’t consider this a kid friendly place or wheelchair accessible despite what they might advertise. If you have little ones it might be very hard for them to stay entertained. And for those who are handicapped and use a wheelchair the tour is rough and full of stairs, narrow paths, and gravel unpaved walk ways. Save yourself the trip it’s cool but not a must see.
  • Very fascinating and educational for us. They also were very accommodating for my husband who wasn't sure he could handle all the walking and steps. Wish I could have been involved in the 2 year test, recommend this for everyone at any age.
