For example, another poster mentioned taking kids to the Excalibur hotel. The Excalibur has go-go dancer entertainment just as you walk into the casino floor...
That was me.

In my defense, I would just like to say that I did not advocate taking kids INSIDE the Excalibur.

I suggested that the OP's older child might get a kick out of seeing the OUTSIDE of the Excalibur because it resembles a very large castle.
On a recent visit to Las Vegas, my husband and I were walking down the strip and passed the following impersonators- Elvis Presley, The Blues Brothers, Michael Jackson and Winnie-the-Pooh. I asked my husband, "Now which one doesn't belong on the strip?"
One evening we walked down and caught the Pirate show outside Treasure Island. The show goes on nightly directly outside the entrance to the casino. The setting looks very kid-friendly, with big pirate ships and the promise of a pirate attack. There was a big crowd gathered for the show, and beside us was a family with a young boy, maybe 8 or 9 years old.
The show started and it wasn't long before the "sirens" and "pirates" started to battle. The sirens were scantily clad and had some, um...dance moves to entice the attacking pirates. Well, I heard the mother of the boy say, "Oh dear, this isn't what I had in mind, not what I thought it would be", and the boy's parents promptly dragged him away. But not before the kid snapped as many pictures as he could with his camera! Hopefully, the photos won't end up at Show and Tell at his school!
Unfortunately, some people realize it before it's too late that LV isn't for the little ones!
