A.S.
Some of the ones you mentioned I had not heard of so I thank you for the suggestions.
Here are my suggestions for kids parties here in Las Vegas:
JUNGLE THEMED: RAINFOREST CAFÉ at the MGM Grand Hotel: Check their website out for more details
ROCK N ROLLTHEME: HARD ROCK CAFÉ on Paradise and Harmon
MOTORCYCLES THEME: HARELY DAVIDSON on the Strip
NASCAR RACING: NASCAR CAFÉ on Sahara and the Strip
MEDIEVAL: TOURNAMENT OF THE KINGS at the Excalibur
I'm not sure of the prices, but some of these venues would be fun.
Here's to a happy birthday where ever you decide to hold it.
