- The casinos are making an additional $7+/day from every vehicle parking on their properties (those who haven't found a way to get free parking, including being on a higher than lowest gaming tier).
- MGM Resorts started the trend, and within months Wynn and Caesars followed suit. The increased revenue in MGM's case was to fund an additional paid parking garage.
- All future projects will probably follow suit and limit the amount of spaces.
Throughout all of this, the only big improvement in public transit discussed has been some kind of rail option going down the Strip in the future. Otherwise, it seems to be that locals will pay more by either paying to park or using ride hailing/taxis. In other words, not necessarily moving us forward in transit efficiency and additional revenue to the benefit of a few companies.
I imagine the impact on visitors isn't that great. I know I won't rent a car unless I'm going outside of the city and it's just cheaper/easier to keep it while I'm staying on the strip. For locals, I imagine it will make some pay more and some switch to off-strip casinos but the higher gaming tiers still get comped anyway.
ADDED: I've been told that one of the issues was increased freeloading by people going away on trips and parking at strip hotels, especially Mandalay Bay but I'm not sure how much to credit that given other solutions that don't involve charging everyone for parking.
Honestly though, this is your experience and nearly decade of car-hostile planning has paid dividends in cities across the country, even if it doesn't work for all use cases. The suburbs and car-centered world only work in a single use case.
