Once you land in New York, you simply need to redeem your voucher at any of the several Hop-on, Hop-off Visitor Centers found throughout the city. In exchange, you’ll receive your Bus Tour ticket. Then, you can start your Tour at any of the stops along the various routes. Just show your new ticket to the driver. And, if you can’t find your way to any of the 30+ stops, the bright red, double-decker bus is pretty easy to spot.
