My first choice would be Huntington too. Great pier, shops, lots of things to watch. Huge volleyball setups, surfers, and so on. Do you know what a Hollister apparel store is? Do you have one by you? If so, then I believe all of their stores have a live cam set up on both sides of the store, of Huntington. You could go see what it is like!

Go to one of the walk up snack places and order some "Strips and Cheese." This was my first introduction as a teen to nachos and salsa. LOL....that was many years ago.

Another great place to eat is at the Sugar Shack. Or Ruby's at the end of the pier.
Newport is great too. It's really nice to walk along the Strand, (Concrete boardwalk) and oggle at all of the beautiful beach houses that are right
on the beach. At the beginning of the pier, they sell fresh fish.
Great place to eat is Charlie's Chili. Or once again, look for some strips and cheese. If you keep walking south on the Strand, it will take you to Balboa Island and harbor. Neat little area.
My DH's favorite thing to do, while there, is watch all of the exotic cars along the Pacific Coast Highway, (PCH.) So if anyone in your family likes that kind of thing, they will be in heaven.
Have fun!
