As a general rule, hotels on the Strip are now charging to park.
MGM Resorts properties varies it a little from hotel to hotel. You can see those details on my MGM Parking post. I have another page with details for parking at Caesars Entertainment properties.
There are still a few places you can park for free, though.
- TI does not charge for parking. They also allow you to opt out of the resort fee if you book with their TV Ad rate.
- SLS/Sahara has free parking and has a conveniently located LV Monorail station (which may be more convenient than a car if you are heading to the Strip anyway).
- Circus-Circus (an MGM property), Wynn and Encore have free self parking. The Venetian, Palazzo and Stratosphere still offer free self- and valet-parking.
Some shopping centers also offer free parking. Crystals (City Center), Fashion Show Mall (near TI and Wynn), The Miracle Mile Shops (Planet Hollywood), and The Shoppes at Mandalay Place all offer free self parking.
