depends if you are driving or flying in!
For JCGC weekend, many people fly into Islip-McArthur and stay right at the airport hotels there (less expensive flights and hotels than NYC) and rent a cheap car...or
if you have no wheels, there is no place near Belmont I would stay at...stay in NYC and take the train...but be prepared to have long lines on the Belmont Special trains on that day post race!
