I stayed at the Best Western Robert Treat hotel and did the commute by Path to WTC and also New Jersey Transit train Penn to Penn station.The Path trains run all night and the New Jersey transit trains stop at 1am.I was really amazed how fast and cheap those connections are.
What I noticed is the hotel was full of European budget travelers doing the same exact thing.The hotels offer free shuttle service from EWR and to Penn Station, Newark around the clock,so people don't need to worry about walking through the wrong Newark neighborhood.Also having the option to eat on Ferry street in Newark is a huge plus and it seems safe even at night
I didn't know that 4 US presidents have stayed at the Robert Treat and so did Albert Einstein.The rooms seem to go from $72 a night to $120.00 a night depending on which booking site one uses and what time of year it is.The rooms are renovated and very nice and the breakfast is free too.
I was amazed that is was mainly Europeans taking advantage of this budget option ,although I did run into an Australian as well.
The ease of getting to and from the airport to the hotel for free alone is worth it.
Don't know if this trend is on the increase, but compared to last year when I stayed in Newark,it really seems to be.
