Group travel has a way of becoming financially complicated long before anyone boards a plane. Costs that seemed manageable in a spreadsheet start multiplying once real decisions get made — someone wants a nicer hotel, someone can't afford the activity package, and the contingency fund that looked generous at the planning stage turns out to be the first casualty of a delayed flight and two unplanned meals.
