Garden view at the Boardwalk is your best bet and even that is easier for shorter stays as well as a stay that is fluid (I mean in that you can try one day but if it is not available you would be okay changing the dates to anytime in October- whenever you can get you number of nights). You will need to be ready to reserve online right at 8am on your 7 month window. Also be willing to use waitlist for a night here and there.
That being said- it is possible but noit very easy.
