Related to Renaissance hotels and exempt properties...
A few years ago, my wife and I stayed at the Renaissance Los Angeles Airport Hotel for a Friday night before a flight to Honolulu the next morning. At check-in, the front desk gave us Platinum Elite breakfast vouchers because the lounge would be closed on Saturday morning. The full breakfast buffet in the attractive restaurant was a very pleasant way to start the travel day.
I made mental note that the Renaissance Los Angeles Airport Hotel would be my first choice the next time I needed a hotel at LAX, especially a weekend hotel. Sure, I would also consider rooms rates and recent reviews, but I would hope to stay at my first choice.
The Renaissance Los Angeles Airport Hotel is now one of those 20 exempt hotels. There are other full-service Marriott Bonvoy properties where I would still get a Platinum Elite weekend breakfast, so the Renaissance at LAX is now at the bottom of my list.
