I'll be in town for a wedding June 14-16 and would like advice on the cheapest way to get from Newark Airport to the Sheraton Mahwah. The hotel site says that it's a $100 taxi ride, which this limited-travel-budget graduate student isn't paying. I see that the light rail service at the airport is undergoing some renovation, so there's a bus I guess I can take to Penn Station to get a train up to Mahwah? If someone can explain to me the steps I need to take once I get my bag from baggage claim (which will be around 5:30pm on 6/14), I'd be most appreciative! Thanks!
