How can I get a travel guide of Las Vegas, NV?

Yahoo has one, lonely planet's web site has one, or go to your local library or bookstore.

Try just going to the local AAA and pretend you are a memmber and want a trip tick with out the step by step directions on who to drive there.. just a local map and their book. Most of the time they don't ask for a card to verify you are a member and if they do just say you forgot it at home.

Go to www.LVCVA.com
It's the Las Vegas Convention and Visitors Authority
They will send out free brochures

The internet is massive travel guide. There is a virtualy unlimited ammount of information to be found. Just google the phrase "las Vegas" with what ever subject you want to know. Like google "las Vegas hotel reviews"
