How much luggage you can bring depends on the vehicle you choose. The Chrysler Pacifica and Mercedes Vito comfortably fit suitcases for a full group plus carry-on bags, while the Mercedes Sprinter can handle even bulkier equipment, such as ski gear or sports equipment.
If you're travelling with unusual luggage — a bike, a pushchair, or musical equipment — it's worth mentioning this when booking, so the right vehicle can be arranged.
