HAWAIʻI · Oʻahu, Maui, Hawaiʻi Island, Kauaʻi
Rehearse your Hawaiʻi trip before you go
Each Hawaiian island has its own face: Waikīkī's city, volcanoes, canyons, and popular nature spots that now need reservations.
Dejavoy is a free game: plan a trip, then play it through day by day before you go, and catch closed days, missed bookings and tourist traps before they catch you.

Traps travellers fall into
In the game these hide among the recommendations. See if you can spot them.
- The “free tour” booth Honolulu (Oʻahu)Waikīkī 'free' or 'half-price' booths usually require attending a timeshare sales presentation; it eats half a day
- A photo with the parrots Honolulu (Oʻahu)Street photos with animals put on your shoulder come with a steep fee afterwards; say no up front
- A swim at Waimea Bay in winter The North Shore (Oʻahu)November to March is big-wave season on the North Shore; check the lifeguard flags and stay out on red-flag days

- At the trailhead parking lot Honolulu (Oʻahu)Car break-ins are common at Hawaiʻi trailheads and beaches: leave nothing valuable in the car, and stash things before you arrive, not in the lot
