CUTE! Your parents look like so much fun! They are so cute!
I love that they have been married 30 years and happily too by the looks of those pics! You are a lucky girl to have that in your life.
Where in Hawaii are they going? I have been to Oahu. I highly recommend climbing Diamond Head, its an inactive volcano, one that helped make the island. Its great! I also recommend going to see the Pearl Harbor monument. Its a moment like no other Ive ever felt. It was incredible.... peaceful! The dole plantation is on Oahu, you can tour that too... take in a luau, go to the state part there - there is a lot going on, and shop in the international marketplace, its fun!
Aloha!
