UPDATED June 30, 2020
Las Vegas casinos and hotels will be able to reopen after the COVID-19 closures starting June 4, 2020. Everything isn’t going to instantly reopen and try to get back to normal, though. I plan to do a series of posts on the topic in the coming days. I am going to start with the most pressing one.

Which hotels are reopening on June 4th?

Caesars is opening Caesars Palace, Nobu and the Flamingo on June 4th and Harrah’s on June 5th. Paris in now open as well.
MGM is reopening the Bellagio, New York-New York, MGM Grand and The Signature on June 4th.
Both companies will reopen other hotels based on demand, but are accepting reservations. All other Caesars properties are currently accepting reservations starting July 9th. Other MGM properties like Aria and Park MGM are accepting reservations starting July 16th. The Mirage isn’t accepting reservations until mid-August.

The Cosmopolitan is opening June 4th. Wynn and Encore are both reopening June 4th. The Venetian is also opening June 4th. The Palazzo does not have a target date and is not currently accepting reservations.

What does reopening really mean?

I’ll get to more details in another post, but basically it means the hotels and casinos are open, but with limited capacity and amenities.
Slots and table games are available, but with limited capacity and social distancing considerations. Many restaurants are open, but again, with limited capacity and social distancing considerations. Valet parking is typically not available, but free self parking is. Clubs, concerts and most entertainment options are still closed.
