Good day!
Perhaps a silly question, but just want some reassurance on my thinking here...

Have stayed at the following Hyatt brands:
Hyatt Regency, Hyatt House, Hyatt Place, and Hyatt Centric.

I need one more and have an upcoming trip to Las Vegas. When searching on Hyatt's website you get results such as MGM Grand, Bellagio, etc.... would those in any way count towards this, or are they simply just affiliates or something? Again, just looking for some clarification. TIA
