Don't lose a day to a missed booking deadline
Hanauma Bay sells out 2 days in advance. Haleakalā sunrise opens 60 days out and the prime slots are gone within an hour. Pearl Harbor's USS Arizona Memorial requires a separate timed ticket. Show up at any of these without a reservation and you're turned away at the gate, full stop.
This cheat sheet is the one-page editorial reference we wish we'd had on our first trip. Every must-reserve Hawaii attraction, with the booking URL, the exact reservation window (when does it open? how far in advance?), our recommendation on when to book, what it costs, and what to do if you miss the window. Plus a counter-list of the things people think they need to reserve but don't.
