I'm looking to go to the USS Arizona and surrounding Pearl Harbor museums during my stay in Honolulu. The tickets from recreation.gov are sold out for June 20th,...but hawaiifun.org seems to have some. I've haven't purchased tickets from them yet but have added to cart and gone to the point of adding credit card information. From my readings, USS Arizona has specific tour times, but hawaiifun doesn't ask for time slots but still says tickets are available.
Am I missing something? Hawaiifun.org seems like a legitimate site, but I don't see how they can provide tickets without request for time information. Has anyone purchase USS Arizona and other Pearl Harbor tickets from them?
Here's the link to their Pearl Harbor offerings.
