Please folks. Leave the kids at home. Vegas isn't for children. Its for drinking, gambling, fucking, tripping, freaking out and losing your mind. Yah yah yah... Excalibur, Circus-Circus, MGM Grand and some other joints try to tell you to bring the kids, but lets be serious:
HIRE A SITTER!
Your kids would love a vacation from you as much as you would like one from them.
Get crazy, get loose, grab your spouse and get a jacuzzi room and fuck like a pornstar between sessions at the craps table and turns at the buffet.
LEAVE THE KIDS AT HOME.
