I know there are shows specifically for kids and specifically for adults but I would like to find some shows both adults and children could enjoy. Something that is safe for them but still palatable for an adult's mind. I have gone to some children's shows and have been bored out of my mind before! lol
Excalibur has the tournament of kings show. It is a medieval knight tournament show with dinner.
My son and his wife took their two boys to this show. They are 7 and 9 years old and both loved it! They were showing me pictures of it and it looks really good for what you pay. I was surprised.
I recommend the Gregory Popovich's Comedy Pet Theater, the kids will love it, and I have a feeling the parents would too.
I would recommend most shows relating to magic as ok, maybe any circus performances, gymnastics etc.
I would say Penn and Teller as well, but they may swear a bit, so not sure.
