I used my 5 day city sightseeing pass which came with a return ticket. I asked for my bus tickets the same day I collected my pass, no problems at all. The bus ticket is valid for a month. On the day, the coach is located on the other building from the gray line office. Opposite the New York Times. The elevators on left takes you to 4th floor and look for gate 410-411. I got on the 8.30am bus, after reading reviews I arrived 15mins early but there were about 20/30 people in front already. This was on a weekday, I dread to think what the weekend would be like. Journey there was smooth and it took exactly an hour. Shops didn’t open until 10am so had to walk about for 30mins. Shops are decent, same fossil smartwatch was cheaper than in Manhattan. Lots of other bargains, don’t forget your discount book when you get off the bus at the visitor centre. I got the 5.20pm bus back to the city, arrived a bit late and left at 5.40pm arrived in port authority at 6.45pm. If you plan to buy a lot, bring a suitcase with you, easier than carrying bags and the bus has spaces underneath to store the suitcases. It was an enjoyable shopping trip, a lot of departure and return times to choose from so you’re not restricted.
