Do I need to make an appointment directly when ordering?
You can make an appointment, but this does not have to be done right away. After ordering you will receive a voucher with which you can easily make an appointment via the website.
Can I change the voucher after ordering?
Yes this is possible! For example, you can extend the workshop or even choose something completely different. Ideal if you find another workshop more enjoyable. No costs are charged for this, you only have to pay the difference in price. The voucher is not redeemable for money so you will not get a refund when you choose a cheaper product. You can easily arrange it yourself, enter your vouchernumber at 'make reservation' and choose 'change voucher'.
What is the minimum age of the participant or passenger?
Take a look at the Specifications section of the workshop of your choice, that is what it says.
What time is the workshop?
When composing your workshop you can specify a reservation request for a day and part of a day. You will receive a confirmation by mail with more information and the exact time.
