For example, having stayed at a number of JW's, I doubt that there is one more deluxe than the Ren Vinoy. The New Orleans properties (I wish them the best) are another example: the JW doesn't seem much different from the FS Marriott across the street, but the two Rens seem a step above.
JW's standards are higher than those of Renaissance & Marriott, to me I'd say they are mostly smaller items but they would be missed if they weren't there (easily overlooked when present but still leaves you with a sense of being nicer than a Ren/Marriott) Hopefully this makes sense
