Sorry if this is a newbish question. Do any Vegas sportsbooks let you deposit cash to set up a temporary account during your stay, and then allow you to place bets on that account with a final accounting of win/losses done at the end of your stay?

The reason I ask is that the last time I was in Vegas during March Madness, getting bets in was a horrible hassle. Long lines, and then on top of that, apparently sometimes the systems were overloaded so if I had like 5-6 bets I wanted to get in, it would literally take 5 minutes per bet to process. And then on top of that, it was just a pain to deal with all the various tickets and carrying around so much cash for wagers. Was thinking there must be a better way, especially if you're making lots of wagers during the course of short period. It would be great if I could just place all my wagers with the book at the hotel I'm staying at, with a final reckoning done at the end of the stay.
