It all depends what you're looking for
We never had a family house down the shore so we don't have the emotional attachment some do
Also, we went different places as kids (Jersey shore, Outer Banks, Myrtle Beach, Florida) that had beaches, so we got to see some different places and what their beach scene was like
Also, we live 20 minutes via back roads from Manasquan / Spring Lake / Sea Girt, so we can go there on a whim
I like the feeling of flying somewhere. As kids, we drove and it sucked. Flying feels to me like you're officially "on vacation." We try to grab the earliest flight possible to avoid any mishaps (delays, weather, etc.) on airlines and at airports where there's ample backup plans in case something happens, and not one flight per day
The only beaches in NJ I'd vacation at would be the aforementioned 3 above plus Brigantine, Stone Harbor, or Avalon. We'd have to get a ridiculously good deal and it would be 3/4 days max
All in for 3 people with flights, rental car and beach front condo for 8 days at Marco Island was 3,500. Spending money got us for another $1500 (dinners, groceries, excursions, wave runners, etc.) so 5k all in is what we spent
It truly felt like a vacation, the flight was 2.5 hours, easy in easy out from EWR-RSW. Yes, it gets hot from Noon-4. Buddy got us into the JW beach/pool for a few days, also TigerTail Beach, dolphin swimming in Miami and airboat tour in everglades. Also rented waverunners, and just went in the gulf for 3-4 hours a day
Dinners on 5th Ave in Naples are pricey, but super nice. Looking at Sarasota / Siesta Key next time, or Sanibel Island (South Seas Plantation) if it's rebuilt by then. South Seas was our first choice but it got crushed by Hurriance last year
