That is a tough question........If you could really care less about the lounge then there would be no reason to pay the price of the JW. I am mostly interested in the breakfast amenity and if you want to explore all the restaurants there are many other Marriott options for sure. If you are solo then I would go with the Aloft in a heartbeat. The AC looks decent and has many good reviews - I don't think you get breakfast though?
I have a little bit of a bad taste in my mouth because I had a horrible bed at the JW - not sure if it was just a "one off room with a crappy bed" but I had the worst sleeps and sweated like crazy in their bed (unusual for myself)?? All three of these being the Aloft, Fairfield and Courtyard have great reviews and look very clean.. We walked by all of them and they all look like they are kept up very well. I would probably gear towards the Aloft or Courtyard as the Fairfield rooms are really "plain Jane"? I found the Aloft in a great location, comfortable bed, decent breakfast and clean as a whistle!...and of course the price point helps too when paying with your own dime.
