Can I pay in instalments?

Yes, and it happens on its own. When a camp takes payment through World Camps, you never pay everything at once unless the camp starts very soon.

You pay the deposit first, once the camp has accepted your request and your 24 hours of free cancellation have passed. The rest is charged in parts, on the dates set by the camp's cancellation policy: each part is charged on the day it stops being refundable. A camp without a deposit works the same way for the whole price.

The dates and amounts are fixed and shown at the Review & Pay step before you confirm, and again on your booking page. They are charged to the card you booked with. You cannot choose other dates, and there is nothing to do on each date.

If you book close to the start, the parts whose dates have already passed are charged together once the camp accepts.
