VIETNAM · Hanoi, Hoi An, Saigon…
Rehearse your Vietnam trip before you go
Vietnam is long and thin: north, centre and south differ in climate and food.
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.
