Since I own 4 timeshares there, it'd bug the heck out of me.
MGM recently sold Treasure Island to Phil Ruffin. Mr. Ruffin is the former owner of The New Frontier. There's still the Saraha and the Strat has plans for expansion. Imperial Palace and the Riveria haven't been upscaled yet and Circus Circus, along with Excalibur are still in the family market.
Vegas only needs to return to the average tourist with less expensive alternatives for shopping, dining and shows and they'll get back to business IF they offer better odds than can be found the local casino's that are within driving distance of almost everyone in America.
We use to be able to find full pay video poker machines on the strip and would play them for a couple of hours per day. Over the last few years, those machines did a Jimmy Hoffa act and haven't been seen since. The average tourist gambler might not understand the odds but, they do understand when $200 is gone in less than 10 minutes. You do that to people long enough they'll quit taking their chances because they KNOW they can't win. Vegas forgot to give the gambler the illusion that he had a chance to win while, in the long run, he never had a chance. Over the last couple of years Vegas assumed that the little guy, the one that had to stretch his dollar, wouldn't mind if Vegas took his money just a little faster with each passing year. Automatic shuffle machines that increase the number of hands dealt from 40 to 120 hands/hours, thus tripling the effect of how fast you lose your money. Changes in rules that gave the house an even larger edge, again speeding up the losing process. Decreasing the odds you can place on a Craps table, again speeding up the process. Double zero roulette tables instead of single zero tables and short pay video poker machines that took you money like a reverse ATM have chased the average gambler from the casino's.
Vegas was never set up to make money off restaurants, night clubs and shopping. Those were all excuses to get you into the casino so you'd drop a couple hundred over a few hours before/after you ate that $5.99 prime rib dinner. People did just that and had fun doing it. Just enough people would brag about how long they played, the comps they recieved or how much they had "won" one day that it kept not only them coming back but attracted their friends as well.
We went to Vegas because the odds were better than the local casino and Vegas offered us more. Now, Vegas offers us high dollar restaurants ($20 for a bean burrito? You've GOT to be kidding me), high priced shows (how many Cirque or Cirque type show can you offer in just over a mile?) and shopping malls where I can't afford a pair of socks. Where's the fun in that?
