Forgot to post this earlier. As per:
https://lasvegassun.com/news/2019/ap...g-without-res/
Wynn Resorts will allow free self-parking for everyone at its Strip properties without restrictions starting [May 1st].
This follows the change last June to stop charging hotel guests for parking and allow validation for visitors given sufficient spend. Good that they're getting rid of it entirely.
I don't hold out much hope that other properties that charge for parking will change their policies. An exec at Cosmo earlier this year mentioned that charging for parking simply doesn't align with the guest experience they want to provide, but they'll continue to be forced to charge so long as such nearby properties charge.
