Caprimax, where do you plan to go?
Some of the major concerns have been at the far ends of train lines, where there may be less people and less crowded sections. If you’re planning to go to Brooklyn or Queens, you should certainly ask about which train lines and which stations are more concerning than others.
If you’re pretty much planning to stay in Manhattan, below, say, 96th street (although you could safely go to the cloisters during the day), you should remain vigilant, but it will never be empty which is what you don’t want. Safety in numbers. If you encounter someone who seems to not be “all there”, keep your distance. They will mumble or perhaps rant and rave. But won’t bother you if you keep away (and try not to stare).
Although the subway cars are SO much cleaner, I try not to touch anything as much as possible. You should hold on to something if you need to stand because you’re not used to the motion. But I’m sure you, like all of us, carry sanitizer and just use it after you get off. If you’re especially nervous, feel free to wear latex gloves and discard them when you get off. I admit that I did that a few times but now I just sanitize and wash as soon as possible. Most people are masked, and many, many are vaccinated.
You will see what you choose to see - if you want to focus on the one creepy guy who rants and raves, that’s what you’ll see. If you want to focus on the locals going about their business, or the high school kids chattering non stop, or the tourists figuring out where they’re going, that’s what you’ll see.
Think about how you want to organize your days. You may choose to start the day taking the subway, but towards the end of the day, when you’re tired (or perhaps laden with packages), may prefer a cab or Uber.
Pre-Covid, I took the subway home even very late, long past midnight. Now, I’m not doing that. Maybe in a few weeks. We’ll see. But by 9 or 10, I’m either waking or taking a cab. (Note: while I feel perfectly safe walking alone at 10, or 11, I know where I’m going. Perhaps until you know exactly where you are, a cab would be preferred).
My advice is to prepare yourself to take the subway. Look at subway maps, maybe some YouTube videos about riding the subway. Become familiar. Then, once you’re here, do so in the morning and see how it feels. It’s a $2.75 investment in testing out your own comfort level. If you don’t like it, you tried and that’s that.
