A retreat itinerary with five stops needs a driver plan and a schedule, not just a bus.
Multi-stop retreat runs are the most common way faith group trips go wrong — not because the bus breaks down, but because nobody built a real schedule around drop-off and pickup windows at each stop. A transportation manager should ask for your full itinerary, including approximate timing at each stop, before quoting the trip.
Mission trips add another layer: if the trip crosses state lines and runs more than roughly 10 hours of actual driving, federal hours-of-service rules may require a second driver or an overnight rest stop built into the schedule. A carrier that quotes a long mission trip without asking about total drive time is skipping a step that affects both safety and your arrival time.
