Your coach journey can be split up into 3 parts
The journey from your pick-up point to the Dover Ferry Port
The Ferry crossing from Dover to Calais
The journey from Calais to Resort
If you are travelling by coach, the journey to resort will generally take around 12 - 15 hours from leaving Calais, the ferry port in France. The journey time can and generally does change depending on how busy the ferry and the roads are, the weather conditions and how many stops are taken along the way.
The ferry crossing generally takes 90 minutes, however you'll need to factor in additional time waiting at the ferry port
