Nah, the boardwalk is pretty awesome. It's still the boardwalk. We saw Harry Potter 5 on the beach there, that was a blast.
The actual beaches in wildwood aren't the greatest, but the boardwalk experience is great. If you want nicer beaches though head south to Cape May or north to Brighton Beach.
Brighton's possibly the sexiest beach I've been to in Jersey. Teeming with wildlife, it felt almost like I was in Cali.
