Hi there!
Sorry for the late posting. I am getting married at the Sandpearl in December - just right down the road from the Hilton. The Hilton is a good choice btw! Anyway if you still need someone for hair and makeup. Try Elena from Epoch Salon. I've gotten several ppl referring me to her so I would say she's worth checking out! She also comes to you which is also good!
As for restaurants, Frenchy's Rockaway Grill has a nice laid back vibe and its right on the beach! For the rehearsal dinner we are having ours at Island Way Grill. Again, another referral with good food and nice rooms for private parties!
HTH! Good luck!!
