Choose a 'Skip the Ticket Line' ticket for general admittance and to skip ahead of anyone who's trying to buy their ticket on the spot. If you're looking to get in even faster, choose a 'Skip All Lines' ticket to get priority access (as well as priority exit on your way out!) and zoom past everyone.
For the real VIP experience, go with the 'All Inclusive Flex Package' and get all of the above plus $15 credit to use on drinks or souvenirs – and best of all, you'll get to arrive at any time during the day! No rushing, no stress, but plenty of fun.
You can also combine your One World Observatory ticket with a range of other New York experiences. Take a guided tour at 9/11 Ground Zero, visit the Statue of Liberty, or take a comprehensive walking tour of NYC before viewing the city from above. However long you have, there's a perfect ticket out there for you.
