Component

Derive party size from parameters already collected (usually custom integer inputs) instead of a dedicated person-count UI.

When to use: Tile or Input form (RequireInput) flows that ask “adults / children” as separate fields, then need a single person-count for occupancy.

Typical place in the funnel: After Input form (RequireInput) or Tile Selection (TileSelectionInput), before Use quotas (UseQuotas) / plan-element selection / Add Position (AddPositionToOrder).

See Entering the number of persons (PersonCountInput) and pattern booking-classic-occupancy.
