You need to spend a little time at different hotel chains. Once you do, you'll never make another post about inconsistency across the Marriott brand.
I hope that I don't sound like a jerk, but consistency was the big reason why I switched to Marriott. You won't find more consistency than with Marriott. I know that every Marriott branded property will meet minimum standards. With others, it was a crap shoot.
I think that you're measuring over and above items; I'm sure you'll agree that every property was perfectly acceptable.
