Tried to book online, no tickets, spoke to hotel who called discover hawaii tours and we got set up by then.
Tickets very limited last minute so book in advance.
Trip was great, memorial to Arizona very good and quite sad to see all those names on the wall.
Not really a trip for young kids, bit horrified that despite a number of reminders in the cinema to turn phones off, there are still people that can't spare 22 mins of respect without having to text or check their phone, after all this is a memorial.
Interesting museum and bowfin visit, makes you appreciate how submariners had to live.
Not much choice for food in the park, so make sure you eat and drink beforehand.
