The subway’s permanent alcohol ban will not be changed on this occasion, unsurprisingly and only somewhat disappointingly (based on SantaCon, it’s probably for the best).

In response to the large turnout expected for the parade on Saturday, some staircases at the 77 Street station on the 6 will be designated as either entry or exit only for the sake of crowd control.
