Hi Jukka,
I went through the same scenario earlier this year and ended up staying at a really dumpy motel (I think Travelodge) for $43.00 that had a shuttle. It was worth it just to be able to clean up, watch tv and rest for a couple of hours. Another option I once saw posted is to rent the cheapest car you can find and park in or around the airport and sleep in that.
Anyway good luck, I don't enjoy spending night in the aiport, but at least it's heated and indoors

Our flight arrives little after 1 AM and our connection is at 6:30 AM. It seems that it wouldn't make sense to check in at the airport hotel for $139.00 as one could stay there for about 3 hours.
Is there a place to spend time at EWR in relative comfort while waiting for our connection to Boston?
