All of the ferry information is at www.davisparkferry.com I'm assuming that you are coming for a day trip to the beach. If you are coming for a longer visit you will have to rent a house. There are no hotels Davis Park. There is a public beach with lifeguards, public bathrooms, a bar, a snackbar and a convenience store. More information is available at davispark.org. It is not an inexpensive day. Parking, ferry, food. Of it is just a day trip I would suggest that you check out Robert Moses State Park at the Western end of Fire Island or Jones Beach State Park on the next barrier island to the west.
Nothing I can add. Great answers to all your questions. Watch out for poison ivy and ticks on the deer. Stay on the walkways. Have fun, hope it's a great day for you
