Hi. Subway to downtown is cheap and fast.
We took yellow taxi although maybe not the cheapest but definetly easy and fast.
A,C,E Subway train to chambers street And when you get off you will see signs for 911 memorial
Uber / Lyft ia easiest however most subway trains go to here or Fulton St - Note that it is wuite close to Battery Park and also the Brooklyn bridge so worth visiting there too.
The big red buses are the easiest...... depends on how long your in NYC....... We purchased a 2 day pass for the hop on hop off buses so easy to use and they run usually every 15-30 mins
Uber 😁
