+ 50% prepayment for booking modification

Modify reservation; proposed solution- There will be a link from home page (or elsewhere) form which will populate a pop-up light box. Clients will insert booking number and last name. After that, the user is redirected to detail of the booking where there are buttons “modify” and “cancel”. By clicking “cancel”, the booking is canceled. Modify will redirect to step where extras are selected and other details can later be modified. This is how we suggest to program it based on general assumptions. Please let us know any specifics in the booking process on the side of the agency that might be in conflict with this, such as payments and refunds, cancellation policy, other terms, etc.
