You require a valid passport to travel to France. Please make sure that you have your passport handy inside your carry on luggage on the coach. Due to recent events in France and the UK border restrictions have been tightened even further meaning that all coaches are checked during both the exit from the UK and on the return from France.
Should you not have a passport with you during the border checks you will not be allowed to exit or enter the UK, this will mean the coach will be forced to leave you at the border should you not be allowed to fill out emergency travel documents with border control.
In the event that the coach is forced to leave you at the border you will need to make your own way out to the resort or cancel your trip, cancellation of your trip will result in a 100% loss of any monies paid to the trip so far as per Wasteland Ski's T&C's.
