If you go on the tour of the dam take them seriously when they ask about being claustrophobic…..and really think about…are you??? I was a little nervous through the whole tour and when waiting for the elevator to take us back up it hit me that I had to get out of there and soon…...Luckily my husband was able to keep me calm and kept reassuring me that we were safe until it was our turn to get on. But one more minute of waiting and I KNOW I would have lost it…..Other than that its an awesome place to visit!! :D
