Yeah so you might not even bother using SNAs...since you are more likely to get a complimentary upgrade. Your call, of course--there's no perfect answer.

I definitely don't recommend the RC--hated the tired and drab/dated decor in the Lakeside Suite even. The public spaces were nice, but that wasn't enough for me. Really preferred the Gwen. Didn't love the JW but then I prefer a smaller property. The Blackstone gets good reviews. The JW and Blackstone have fewer suites proportionally, though. (You always can find out how many suites and rooms a property has by finding the Hotel Details section of the marriott.com website for the property.)
