Adding or removing a guest can affect more than a per-person total. Rooms, cabin occupancy, vehicle choice and private arrangements may all depend on the original group. Ask for a revised quote before assuming the change is simple arithmetic.
Identify every affected service
Check accommodation, activity places, transfers and meals. Supply the new adult count and children's ages where relevant. If the group changes its rooming preference at the same time, say so explicitly rather than expecting the organiser to infer it.
Wait for the updated arrangement
Confirm that the new places or cabin configuration are available and understand the applicable terms. A quotation for one group size does not guarantee a different vehicle or room category at the same unit cost. Keep the revised total and itinerary together.

Tell every participant which version is current. Avoid forwarding an old confirmation alongside a new payment request without explaining the difference. This is especially important on busy dates when the original arrangement may no longer be interchangeable with another option. Clear version control is a practical travel habit, not just an administrative detail.
