1. Official sources first
We use city, county, tourism-authority and contracted-operator pages. Blogs and search snippets are not treated as current operating evidence.
VERIFICATION METHOD
Uncertainty stays visible.
CITY TOUR CHECK is an independent planning guide that turns official public information into a date-aware summary. It is not a booking operator.2. Validity and checking are separate
The effective period says when a rule applies. Last verified says when a person reopened the source. They are not the same claim.
3. Conflicts stay visible
When official pages disagree, or holiday, inventory or weather conditions cannot be resolved, we do not pick a convenient answer. The result falls back to Check required.
What each date result means
The stored official weekday and season rules include the date. Seats and same-day changes still require an operator check.
An official closure, seasonal pause or non-operating day excludes the date.
A source conflict, inventory, holiday, minimum group, weather or coverage gap prevents a safe answer.
Not a real-time operating guarantee
Before payment, reopen the official booking page and confirm seats, cancellations, meeting points and contact details. Emergency closures can appear later than the public source.
