Empire State Building
There's no denying the view from the Empire State Building's 86th-floor observation deck is quite the sight to see, but you may have to compete for a glimpse. And though the $18.45 entrance fee may grant you access to the top, it doesn't stop you from standing in long lines in the lobby as you wait your turn up the elevator. If you want to save on time, you can purchase the $41.52 Express Pass tickets, which allows you to skip the hordes and jump to the front of the line. And, as if that isn't enough, you can also spend an extra $15 to go the rest of the 16 flights to get to the very top of the building, or the 102nd-floor observatory.
