It is really helpful. Because of the huge population of Southern California and it's close proximity to Vegas, L.A. gets a huge portion of the local casinos' ad budgets. Check out your local library or newsstand because this is an excellent resource for finding the real steals on room rates. However, access to Vegas from Southern California is so convenient, that the casinos sometimes offer specials to try to lure Southern Californians on an impulsive decision. You can usually cancel later.
Most casinos offer a very liberal cancellation policy, but be sure to ask, just in case.
Don't be afraid to apply leverage. From reading the Sunday L.A. Times and the multitude of resources at our Travel Center , you should already know a good deal when you hear one. Use this bargain rate to barter with the hotel desk person. The casinos do NOT want to lose a customer to a rival casino. These special savings are just for the asking, but you MUST ask for them to get them.
