<p>I never cease to be amazed by your Ds! For your younger D, I would think getting from the airport to Manhattan is the easy part. She can take a Carey bus or a taxi. It's navigating the subway system and generally getting oriented in NYC that I would find challenging. </p>
<p>My older S was once scheduled for a field trip to NYC. He got to the school, saw a yellow bus pulling away, thought it was his, rushed back home for some money, rode the subway to the Greyhound station and took the bus after finding that Amtrak would get him to NYC later than the bus. At the Port Authority, he got directions to the Museum of Jewish History, by which time I tracked him down and told him to head home: the bus his class was supposed to be on never made it out of Cambridge as it developed mechanical problems before leaving the garage! So he looked around the museum a bit, then went home the same way he'd come: by subway, then Greyhound, then subway again. I can tell you it was a learning experience, all right, for him and for us. He was 15 at the time and much less savvy than your D.</p>
