    How we make these guides

    1

    Official sources first

    Fees, hours and rules come from operators and official pages where we can find them, with the source noted in our research.

    2

    Honest about gaps

    When we cannot verify a number we say so and give a range, instead of printing false precision.

    3

    Dated and kept current

    Every guide shows when it was last updated, and we re-check prices and schedules on a regular cycle.

    4

    Free tools, no sign-up

    Budget calculators, maps and checklists that run in your browser. Nothing is stored or sold.
