Here is a polished UK English version, keeping the tone clear and suitable for a museum website:
Admission & tickets
A valid ticket provides access to all exhibitions, unless stated otherwise. Some special activities or events require a separate ticket.
Tickets are personal and non-transferable. Tickets that have already been purchased are refundable in some cases.
Children up to and including 18 years of age have free admission.
Opening hours & visiting
Bonnefanten is open from Tuesday to Sunday. The museum is closed on Mondays and on a number of public holidays. Current opening hours can be found at Practical information.
The museum reserves the right to temporarily close galleries or artworks, for example for restoration, installation or special events. No refund can be claimed in such cases.
Visitors are asked to follow the instructions of museum staff.
Groups & educational programmes
Groups of ten or more people can make a reservation in advance via educatie@bonnefanten.nl. A reservation is confirmed once the museum has provided written confirmation.
Additional arrangements apply to school groups and educational programmes. These will be stated in the confirmation.
Photography & use of images
Photography for personal, non-commercial use is permitted in the permanent collection. Please do not use flash or tripods.
Different rules may apply in temporary exhibitions, as specified for each individual exhibition.
Commercial use of photographs taken in the museum, or of works from the collection, is not permitted without prior written permission. Please contact info@bonnefanten.nl for more information.
Liability
Bonnefanten accepts no liability for loss, theft or damage to personal belongings during your visit. Please use the lockers at the entrance for valuables.
In the event of damage to artworks or museum installations, the person responsible will be held liable for the full cost of repairs.
Privacy
Bonnefanten handles personal data with care. When you purchase a ticket or register for activities, we process your data in accordance with the General Data Protection Regulation (GDPR). More information can be found in our privacy policy at bonnefanten.nl/privacy.

I’ve used UK English conventions such as “programme”, “non-transferable”, “public holidays”, and “admission”, while keeping the wording natural for an international museum audience.
