There's this subtly named collection from House Industries:

Thanks for the suggestions.

so flamboyant or even tacky is okay

Right up my alley!

I'd do up something in some design software, but if you want something ready made you could go with a neon-esque font...

Or, how about something triline...

...something inline...

Prismatic would be fun.

What pt sizes are you using? Vegas is a dynamic town!!!

Odd we didn't make an appearance on your request - http://www.fontdiner.com/menu_vegas.html

You’ll have to do better with Google, Stuart—“Las Vegas Font” pulls up various freebies and House Industries, but no Font Diner (at least, not on the first page).

New site should fix it :D

Thanks for the additional suggestions!

Lamplighter and Leisure are awesome!
