Depending on when guests ask guides to change the details of a trip, the details of the deal differs.
1. If you ask before a tour
If you ask guides that you want to change the details of your trip by the day before the tour, you can let guides check whether the price and the details will change dramatically. As long as guides change just its order or little things like this, it may not be necessary to rebook a new tour.
If the details change greatly including its fee, guides need to cancel the tour once and let guests book a new one again. At this time, canceling from guests may require a commission fee. Cancel it from the guide side and send an offer again, then let the guests book and settle a payment.
2. If you ask on a tour
If you tell guides that you want to change the details of your trip on the day of the tour, guests cannot rebook a new tour on the same day because guides cannot send the offer of the tour which is held on the same day. If guides and guests change the details of the trip on the appointed day, please consult between guides and guests first before doing so. Double check the extra fees and these kinds of things as well.
