Packer- It's not worth the time and aggrevation to try and bet sports in Las Vegas and hasn't been for a long time. The places don't want any action over $100. The sports books are there for the casual bettor, the rube tourist and any square that wants to bet their ripoff parlay cards. The sportsbook is just a part of the overall hotel-casino experience just like the coffee shop, buffet or bingo room.
You could get down forty dimes on a baseball game but you'd have to spread nickels and dimes around so it would take a while. Your twenty five dime parlay at one place is a pipe dream. You could get it all down but you would have to keep the parlays at about a nickel at the bigger joints and about two hundred at the smaller books. You'd have to spread it around but you could it all down.
You can't bet chips anymore, just cash. You can't go over ten thousand in a twenty four hour period in any one book and any play over twenty five hundred and they will write down some general information about you such as your description and the play you made. The ten dime limit is a Gaming Control Board idiotic regulation and very easy to get around. You just keep the plays under the radar and bet them at different windows and on different shifts. If you keep the plays under the twenty five hundred, they won't write anything down but they will keep an eye on you so I recommend a bunch of nickel plays and they won't say a thing.
As I said, Las Vegas isn't in the gambling business anymore so stick to offshore betting.
