Yes. We booked 11 months ago. It is always busy with F & W, Halloween and Jersey Week...I think there is a marathon as well (there was in 2019). October is the 50th Anniversary.
People are cancelling late this year, so keep trying and perhaps do a split stay in hopes of getting one or the other resort for the other half of the stay. Any other year I'd recommend finding another destination, but circumstances may work in your favor, though you likely won't find any "deals" or specific resorts or room sizes. Keep trying as rooms will appear and some lucky person will get them - maybe you! Good luck!
