I looked it up online and this is what it says about the toll -
"Tolls
To get to New Jersey, you don't have to pay any tolls, but there is a $6.00 toll when you return back to the City through the Holland Tunnel"
$6 isn't too bad since my hotel room is only $82. There's supposedly a train station nearby the hotel and there's a stop on E23rd St and 6th Ave, so about a 5-6 block walk. 😳
