How about the Hayt Regency in New Brunswick, NJ. Its close to CH, its a nice place, the the non Jewish hotel staff are aware that you cant do certain things on shabbos and are fast to help out.. If you want you can even go by NJ transit. The train stops literally a short block form the hotel. You have a (770 shaped) chabad house twenty minutes walk from the hotel. The area is a college town (Rutgers). 5 minutes away you have some kosher restaurant's in highland park.
