Well if peeps feel the need to have forms of entertainment available, AKA a real boardwalk, then Pt. Pleasant/Sleezeside I can understand. Belmar and Pt. have their share of punks/traffic and parking issues too.
If we just need a place to gather and maybe grab a bite/grog and not have as much of a parking/punk situation I would recommend Long Branch, Pier Village. Way more upscale and plenty of places to eat and definitely less punks...Maybe more Jersey shore housewives but I'll trade that anytime. Of course anywhere further south of Sleezeside is better too. Sleezeside, Belmar, Pt. are all kinda touristy and you get you're share of wound up NORF JERZEE/Staten Islanders who seem to go WONKO once they are near the ocean
And save the flames fellas, my GF is a Bergen Co. resident and I have family on the island
These are just opinions/suggestions, not my trip to run so whatever you guys decide, I'll try to make it.
