Some travel information is inspiration. Other information determines whether the trip works.

For entry requirements, start with the destination government's official immigration or foreign-affairs source and confirm guidance from your own government's travel service. For schedules, restrictions, and closures, look for the operator or authority responsible for the service—not only a summary written about it.

Record when you checked a fact and check it again close to departure. If two sources disagree, do not average them. Treat the disagreement as unresolved until the responsible authority clarifies it.

A useful guide should help you ask the right question. It should not disguise an old answer as a current one.
