Beach Club Villas. Boardwalk is boring at night, and you can just walk there from BCV if you want to. BCV has better pools and I like the atmosphere more. It's also right next to the YC which has the Yachtsman (great restaurant).
I'd say Beach Club Villa. I havn't been there, but i'm goin this summer, and i've looked @ lots of pics and brocures and stuff, and it seems really great
