The Hyatt Regency's website says that their self-park is $15USD/day for hotel guests (no in and out). I guess you need a real insider who knows this area that could suggest cheaper parking. But that rate is really not that high. There might be a way you could park at a trainstation on the outskirts in NJ for cheap or nothing and then take the train in. But I don't know if this is possible or where you could do it. ...Maverick
