For groups of 25 people or more: This question is included in the terms and conditions Art. 6 and Art. 8

For groups of less then 25 people: We understand your concerns if some of your group don’t know if they want to join this is normally a difficult situation. It is possible to book only for the people you are sure will go along (we always keep the minimum number for the particular activity you are trying to book). This is however only possible for activity’s that are hosted by our own hosts (which is about 80% of the activities on our site). The rest of the people can pay in cash with us on the day of the booking. Let us know as soon as possible how many people will join (no later than 3 days before the start) so that we can bring plenty of materials needed for the extra people in your group. Contact us and ask us what activities this is possible for.
