Could I host a really small wedding? Reserving the picnic tables?

Size wise, it would be good for a small outdoor wedding. I've seen weddings over there, where they had easy ups, tables, and chairs. You will have to contact the Bergen County Parks Department. Good Luck

Call the palisades parks dept or palisades pd desk and ask, but you'd likely need a permit
