We will be on the Sept.23 cruise to Hawaii from Vancouver. We will be in Honolulu on October 4th and staying 2 days in a hotel. We booked a tour of the USS Arizona for that afternoon with hotel pick up and then an ATV tour of Kualoa Ranch the next day with hotel pick up. I was able to research all the possible Royal Caribbean excursions at Honolulu and was not wowed. If you book Pearl Harbor through Karma Tours, you are guaranteed a ticket. Hope this helps.
