How we work

A travel guide is only useful if you can rely on it. That's why Marnival works to one standard for every guide, and shows you where the information comes from. New guides follow it from the start; we are bringing the older guides up to it step by step.

An official source for every fact

We take prices, opening hours, timetables and rules from the source: governments, transport operators, museums, park authorities and tourist boards. Every guide ends with a list of sources, and in new and updated guides the source also sits right next to the fact. If we can't find something at an official source, we say so.

A date on every guide

Every guide shows when it was published and when we last checked the facts. Rules that change often, such as entry requirements and visas, we check more often. If a guide has been updated since publication, it says so too.

Amounts in euros

In new and updated guides, we convert prices in other currencies to euros, with the exchange rate and its date. That way you know roughly what something costs, and how old that figure is.

Estimates marked as estimates

Drive times, walking distances and how long you need somewhere vary from person to person and day to day. We call those estimates, so you don't mistake them for fixed facts.

Corrections

Has something changed? Email info [at] marnival.com. We check it at the source, update the guide and add the new check date.

Independent

Marnival has no paid placements, no advertising and no affiliate links. If that ever changes, it will say so on this page and in the article itself, and any advert will always be clearly labelled.

Photos

We use royalty-free photos that show the real place, credited to the photographer. Never AI-generated images.
