Yes. If an expedition is full, start the registration the same way: go to the trip page, click “Reserve Now” and follow the prompts. The booking system adds you to the waiting list instead of confirming a place, and no deposit is needed to hold your spot on the list. If a place opens up, we will contact you and you pay your deposit then. If you would like us to suggest a similar trip or a later departure, call us at (877) 234-3002 or email hello@christianexpedition.com.
