Two friends and myself went to New York for the HOPE conference in Manhattan. We drove there but we're midwesterners so we didn't want to drive in the city proper. Our plan was to drive to New Jersey, leave our car at a friend-of-a-friend's place, and then catch the train into the city.
All went well until we were on our way home. The friend-of-a-friend was supposed to pick us up from the train station and drive us 5 minutes to his house so we could get in our car and head west. But he wasn't answering his phone.
While we sat there wondering what to do, I saw a pizza place across the street that said "free delivery" on the sign. I joked that we should order a pizza, give the address where our car was at, and then ask if the driver would deliver us as well. Without laughing, my one friend said, "let's give it a try" and strode off towards the restaurant. We explained our situation and a few minutes later the pizza guy was delivering the pizza, and us, to our car.
I'm actually planning a trip with a friend through the Northeast Regional. You can start at the White House / Smithsonian (seeing all of the history there), hop on a train to Philadelphia to see the liberty bell + the original capital of the country, then hop on a train and continue to NYC / Broadway and watch Hamilton.
No car (or airplane) needed. 100% trains / metros.
Train is more expensive for good reason! Its a much better experience. If we're talking about the price of Uber-rides / Rental Cars from NYC to Adirondacks... I bet you that the Train to Philly or even Washington DC will be cheaper than a rental car + all those miles you put on it!
So IMO, save your sanity and go with the train. But the busses exist if you really need to cut back on $$$ even more.
Now, frequency on SEPTA's Regional Rail lines has tanked during the pandemic, so using it may not be as practical as it once was. Haven't checked recently. Hopefully they get service back to reasonable levels.
- Trains get to skip traffic, but rental car might be cheaper if you're splitting it with friends.
- Trains do break down or hit delays sometimes, but traffic is always a risk on I95.
- Buses are the cheapest but have random people (dice roll) and traffic.
- Parking a rental car might not be cheap in a city center but can be a wash depending on transit costs. Again, parking cost can be split with friends.
So my decision is usually situational.
And yeah whenever I visit NYC from here it's always by train.
I was planning on mostly wandering around aimlessly (actually, I'll probably still do that :-) ). But I'm all ears for any "must see" locations.
Liberty Bell + museums are the main thing I know about.
The South Street area is also home to a bunch of mozaic murals by Isaiah Zagar, which are definitely worth checking out. There are official tours, but you can also just check out the neighborhood map here and explore some of them on your own: https://www.phillymagicgardens.org/about-us/mosaic-mural-map...
If you like walks, check out the Schuylkill River Trail - it got caught up in the recent flooding so I'm not sure what kind of shape it's in right now, but I assume it'll get cleaned up pretty quick if it hasn't been already. The view of 30th Street Station and a nearby USPS building is pretty cool at night. I've heard it can get a little sketchy if you're down on the trail at night, but as a 6ft tall white guy I never ran into any issues on the route walked home from work for ~8 months. Your mileage may vary, but the worst thing I ever encountered was kids my age smoking weed down by the river.
You can also take a detour at Broad St up to City Hall (take the Broad Street line subway up and back down if you're tired). See the hall, see the Masonic Temple, see the smallest "LOVE" sign ever at Love Park. Back towards Old City there's Thomas Jefferson's little place while he was writing it, Declaration House. There's the oldest continuously inhabited street in America, with a little art walk on Fridays around there. And of course there's the Art Museum and Waterworks behind it.
If you want to speed up your whole trip, make strategic use of Philly's Indego bikes. A bike is a great way to tour up the Schyulkill, to get to the Art Museum, and head north along the bike trail past boathouse row.
SF is also one of the better US cities in this regard. I spent several months in SF without a car and rented a car exactly one weekend to get to some further out hiking. There are actually plenty of transit accessible natural areas.
