Vegas sportsbook logistics - How do you navigate making the rounds to check lines, place bets, store cash, etc.

With so many sportsbooks in Vegas, how does a person keep up with knowing what lines are being offered where? They don't give out that information over the phone, so you have to drive around, burning gas, paying for parking, etc. just to look at the board at each one, right? That would be a never-ending loop and there are far too many sportsbooks to do that with anyway. Do you learn from word of mouth, which ones are most likely to offer numbers that are most likely to be different than the majority, then hone in on a handful of places that you frequent each week, then visit each one every day? Do they all have aps with real time numbers? Do you have to download an ap and clutter up your phone with all of them for each sportsbook you want to follow? Is digital online betting making it so that you don't have to visit in person? Wouldn't you have to have money on account to do that, just like with offshore? Is ID always required, even if you place bets in person? 

If a group of sportsbooks are run by the same parent company, and the line changes at one of them, does it change simultaneously at all of them under that umbrella?  

I've also wondered if cashiers get mad if you were to hand them a losing ticket, just so they can scan it to confirm that it lost, for those of us who don't trust ourselves when it comes to not throwing away a winning ticket by mistake. 

When betting in person, are there casinos with bank branch offices inside where you withdraw and deposit cash so that you don't have to walk around with on your person? Is it optional to have money on deposit? If so, can you leave it there and have the balance automatically updated like offshore so that you don't even have to visit a cashier? 

I just don't see how you drive all over town checking lines, deciding when and where to bet, then retrace your steps once games have ended to collect your winnings. Sorry if these questions are dumb, but I've never been in a sportsbook before and don't want to wait til I get there be educated on how it's going to work, especially if it's not my home city and I'm just coming there for the season, beginning week 1.  

Ok, so when you download an app, does that app make it clear that the lines being shown by that app are valid for sportsbooks  X, Y, and Z, or does each sportsbook have it's own app?  For example, if a MGM or a William Hill is responsible for creating and changing the lines for multiple sportsbook, which apparently they are, do you download MGM's app and William Hill's app, then bet the app without being sportsbook specific, then when you're ready to cash out, you go to any of their sportsbooks who will be able to pull up your account and hand you your cash? 

According to a website I found which lists sportsbooks (not up to date), that would mean I could pick up my MGM winnings at Aria, Bellagio, Circus Circus, and more. And I could pick up my William Hill cash at Arizona Charlies, The D, Ellis Island, Four Queens, Gold Spike, and more. True? 

I'm assuming then that if I don't like technology and I do it the old way, I have to put together a string of places to visit which include one sportsbook from each of the major conglomerates, knowing that the lines will be the same at each sportsbook within that conglomerate. So if Joe walks into Aria and plunks down enough cash to move the line, he doesn't just move the line at Aria, but at all the MGM sportsbooks at once. If it's an independent sportsbook, or 'local' (as the youtube videos I've watched are calling them), or they don't have an app, I just have to do there. 

And I still don't want to pay to park, especially when I'm only going to be inside for 10 minutes.  

General question that would give me idea on other markets..

How much can I bet one casino (they don't know me) late in week on an NFL game?

What about the money though?

Maybe I'm non-baller but I'd hate carrying $20k.

I like the idea of betting 9 games... But at most you are graded 6 wins or losses.. Cut down on variance and cash needs

I think some people rent scooters to go from casino to casino.  That was a very long time ago,  so I don't know if that still works.  They'd park the scooter right outside the casino entrance and not in the garage.

A cashier is there 9 to 5 or whatever hours.  Most of them probably don't care what you ask them to do.  But I wouldn't collect 100 losing tickets out of the trash and ask to have them scanned.
