It wasn't very friendly to those with disabilities. My mother wanted to go here for so long and finally felt well enough to come. But she is wheelchair bound and also needs to use the bathroom frequently. When we got there we had to wait 20 minutes or so to get in to the exhibit area, then ten minutes after we finally got in she needed to use the bathroom. There is no bathroom in the exhibit area so we had to go out and down to the basement for a bathroom. Then when we finally came back up we were told we would have to wait in the very long line again. My mom was so discouraged and worn out that we had to leave. Very disappointing
