When you look at NYC you have to consider that 1 hour (drive) stretches from 30 to 50 miles depending on traffic. In addition the purpose of the resort as I understand it is to provide activities for the guests that they can't find outside the resort area, they are lower quality, or it is unsafe to step out, which is definitely not the case for NYC.
If you do want to find the resorts in the area you would have to go far in Long Island like
You can probably find a complete list here though I have to warn you that you will be looking at 2 hours minimum commute to NYC. There are resorts on the Jersey Shore or in Connecticut but you are looking at commute a lot longer then one hour (probably 2.5+).
My very serious suggestion is to abandon the private resort idea when it comes to visit NYC as you will miss the whole point of The City(crowds, tempo, etc)
