How we check prices, rules and times
Every price, rule and time from a seller or operator comes from a named source and shows the date we checked it. Official sites come first, and any traveler report is labeled as a report.

Where our facts come from
We start with the seller or operator that runs the thing you want to book, then work down this list.
- The official attraction or operator, for prices, hours, entry rules and cancellation terms.
- Official public bodies, such as the Paris tourist office, for what an operator's own site leaves out.
- Partner data, such as offers from Viator's Partner API, for what a package includes.
- Reliable guides and reference works, when no official page covers the point.
- Traveler reports, for queues, crowds and confusing instructions only.
A lower source never overrides a higher one. A traveler report cannot change an official rule.
How we date every fact
Every price, rule and time sits beside the source it came from and the day we checked it. The date is the day we read the source. It does not promise that the fact is unchanged today, so read it before you rely on a price or a timetable.
When a price from a partner was more than an hour old as the page was built, the page shows “Check current price” in place of the figure. A value we calculate, such as a sunset time, says so where it appears. A value we could not find is shown as unknown and is never shown as zero.

When official sources disagree
Official sites sometimes say two things. We show the value from the page whose main subject is the rule, such as the rates page for a price or the planning page for a booking window, and we give its date.
A newer official statement outranks an older one. We never average two values or pick the one that suits a plan, and no guide, partner or traveler report overrides an official page.
When the difference could change what you do, the page adds one plain sentence saying that the official site states it differently elsewhere, and what to check before you book. Our Eiffel Tower tickets page does this for its booking windows.
What we never publish
- Ratings, reviews or booking counts without a named source and a date.
- A price without its date, or an unknown price shown as zero.
- Availability we have not checked live.
- Savings claims measured against a list price.
- Accounts of a visit written as if we had been there.
Commissions have their own page: how we make money. Who runs the guide is on the about page.
