cab fares

We usually rent a car in Vegas, but this time my wife is abandoning me and making the trip with a couple of girlfriends and they won't have a car. Could anyone give me an average or typical cab fare from Ballys to downtown and from Ballys to McCarren? Just trying to get an idea of cost so they don't get taken.

About $20 to downtown and about $13 to airport. Use this link, it's not 100% accurate of course since it is based on only distance, not any wait time in traffic and/or lights but it will give you a pretty good idea.

Don't forget to factor in the expense for a tip.

Thanks a lot for quick assistance.
