Group rates

• A reservation is necessary. Otherwise we will not be able to process your application and you will not be eligible for the group rate.
• Children's groups can book for a visit on Saturday and Sunday. During the school holidays it is also possible to make a reservation for a visit on Monday to Sunday between 10am-12am and 3pm-5pm.
• You can change or cancel your reservation free of charge.
• To be eligible for the group rates, you must book at least 1 week in advance. After that, the regular entrance fees of the museum apply.
• The maximum group size is 20 children. There is no minimum.
• We think it is important that there are sufficient supervisors. That is why we offer a maximum of 8 (adult) supervisors per group free entrance. Additional supervisors pay the regular entrance fee of € 17,50.
• We ask supervisors to stay with the group. They are responsible for the children during the museum visit.
• You can pay with pin (cash is not possible) at our cash register, based on the actual number of people based on the above rates.
• Eating and drinking in the museum is only allowed at the picnic tables in the entrance hall, in the museum harbor and during a visit to Professor Plons on the terrace (outside).

A maximum stay of 1.5 hours applies to the children's-activity-exhibition Professor Plons. Afterwards, the children are very welcome in the museum harbor.
