This is true at Bellagio, Aria, and Wynn. It is more true for NLHE than PLO. Not true for mixed games, but big mixed games aren't running that much except during the Series. Does "Reserved" mean a curated or private game? Do you need to be an amateur / fish / whale, have a good personality and loose style, or know someone? I assume that open high stakes NLHE games would attract too many obnoxious GTO nerds.
If you are that interested in a Reserved Game then you can call the poker room in question and get additional information. Some games will allow 'Randoms' to sit after a certain period of time and/or if the Regs don't show up. Hopefully whomever answers will have intel for you or at least put you in touch with the 'host' of the game.
It took Brad Owen a very long time to get into the 'new' Aria game hosted by Justin Young and others.
Wish you well .. but IMO if the table is not full and you flash a brick or two then you will find your way into some of these games. GL
Yes these are private games. As mentioned, if you are a random schmuck no poker results on the web, with loads of cash, and the host can verify these things, you may be able to sit. Contact the room to get in touch with the game host about 5days in advance…
