Hi. This will be our first time visiting Honolulu. We will arrive on December 26th and leave January 2nd. We already bought our tickets for Pearl Harbor. We are curious, what are some other things we will want to see/do? But yet, we don't want to be super busy. I thought about a day trip to Big Island through Hawaii Tours. They take you over the live volcano. Its a reasonable price. I want to get pointers from you more experienced people.
