Monorail to Hilton, do both Star Trek Experiences, Luxor motion ride (Search for the Obelisk) is top-notch, there are others at other casinos...

Touristy stuff - Mirage volcano, TI's pirate show, Wynn's Lake of Dreams free show (gotta buy a drink - good chance to let her have some champagne for winning the contest), Bellagio fountains.

Every woman I know can window shop for hours, and Vegas has some of the best - Bellagio, Wynn, Caesars should fill the bill.

Along the same vein, every gal loves to be pampered, so how about a spa-day to get ready for the contest, or to calm down afterwards?

Although I consider myself a "dirty old man", long-gone are the days when I looked for clubs that admitted 18 year olds - so I can't help you out on that one!

Free shows - think magic, parrots, etc, various properties. Mid-level shows - think magic (she's beautiful, so she might get called-up to disappear), singing (Mamma Mia? @Mandalay Bay). If she's into fish, do the Shark Reef at Mandalay, or how about Elvis or Liberace museum for tacky Vegas?

Odd-ball stuff: shooting range where you can shoot a machine gun? How about that place where you simulate free-falling, by floating on a cushion of wind? Think: only in Vegas, you can't lose...

You'll be the coolest Dad if you get her a limo for a night with her friends - they can go all over the place, see the lights, etc...

HAVE FUN!
