You can change things concerning the itinerary of a tour as a guide, but you must agree on changing with guests. Guides cannot change itinerary or reservation unilaterally. Please make sure there is no misunderstanding between guests and guides to change it. Also, expense for the trip of the appointed day incurred by changing should be considered by guests and guides. TOMODACHI GUIDE is not involved at all.
In the case of a change in reservation that a tour date is shifted, cancel the tour from the guide's side once, in order to apply travel insurance. Then the guide will send an offer to guests and they settle a payment.
