Can I drop someone off at the Door so to speak and then go park

You should be able to get pretty close. You won't be right up to the door of the stadium but the Battery has streets you can get close with and then park.

There are drop offs at The Battery.

Very close

Close enough

You can get pretty close for a drop off

If you can deal with the traffic, you can get pretty close.

Yes you should be able to...
