Where do you pick up will call tickets from the National Park Service at Battery Park ?

sry,Don't know surly

There is a will call booth inside the ticket area.

You may also opt for an online booking. In case you are looking for travelling more than a couple of places in the city, I will suggest you to go for a new York city pass It helps you with great discounts

There is a will call counter which you will come across before you board the ferry

Yup

Yes
