There was a long thread here about when Marriott changed in the early 2010s.

I don't like the Courtyards for the lack of microwave and refrigerator (and the lack of free breakfast, which I guess might change come August?).

However, I like the new setup where the bed is against the bathroom wall rather than your neighbor's wall where if people are humping next door...

Also like the tall wall/divider between the toilet and the sink.
