Carry the passport used in the application, visa grant notice, return or onward ticket, first accommodation or operator details and evidence of sufficient funds when requested.
An eVisa permits the holder to travel and request entry clearance; it does not guarantee admission. The officer may ask where the traveller will stay, what the visit involves and when the journey ends. Answers should match the submitted purpose and current bookings.
Store essential evidence offline. Airport Wi-Fi and roaming may not work immediately, so a PDF folder or printed set containing the visa, ticket, first address and operator contact is useful. Keep route-sensitive yellow-fever evidence with the passport where current health rules make it relevant.
If a booking changes after approval, carry the replacement and explain the new plan honestly. A real change supported by evidence is easier to assess than an answer invented at the desk.
For a self-booked Dutch journey, keep one short chronological summary showing the international arrival, the first reachable property, the main safari or island segment and the confirmed departure. This makes several separate reservations easier to explain without altering any original booking.
