They have really made this attraction nice since the last time I was there years ago. The museums are so much more comprehensive and the grounds there are so beautiful now. This is an incredibly moving site and you really should not visit Oahu without going here. It is quite a process to get a tour time if you are not a part of a formal tour group (which I never am). We missed going a few years ago because you have to get there very early in the morning to get your tickets for later in the day. I think the tickets you get then are free. I recommend getting tickets online and those are $7 each.They become available about six months ahead of time and you need to get them then because they fill up. I say "about" because I set a calendar reminder for myself 6 months out and they weren't available and I had to keep checking until our dates showed up. Also, when they say you can't bring bags in to the attraction at all, they are not kidding. So, leave your bag in the car, or be willing to check it in there before you can go in. You will not regret any hoops you have to jump through to visit Pearl Harbor. It is worth all of it and more.
