What are the best heliports and costs to land/park at a New York City
Heliport? It looks like the West 34th street one has about 15 pads.
There's one over at East 30th, too, as well as one down on Wall
Street(Port Authority operated), but they don't appear to have as many
pads.

Looking for experiences, comments, etc. on these. Is a reservation
required? Limit to parking time?
