Travel nightmare

My dream train journey to and from Cannes is rapidly turning into a nightmare.
Got to Lilles to pick up the Eurostar for the homeward leg through the tunnel only to find out the service has been suspended for 24 hours due to a trackside fire....in London!
Am currently on a train heading (hopefully) to Calais where the plan is to try and catch a ferry to Dover. Failing that will have to stay overnight in Calais and get a ferry in the morning.
Having just had one of the most sleep deprived working weeks of my life I'm feeling surprisingly calm and chipper not sure how long it will last.
