Thanks for all the suggestions, finally I chartered a small bus and driver, we have driven all day and are in Calais at the eurotunnel port. (I also sold tickets on my rented bus to other stranded people to cover the cost of me and my team (cash only), just to break even not for profit)
In the mean time I called a friend who bought a clapped out old mercedes sprinter in the UK this morning and is ariving on the next train from the UK, we will get in and we are booked on the next train back to the UK!!!
When we get back we will hopefully sell the van for as much as we paid. (Add in the refund we are getting from the airline and this actually saved money on the trip back, it just cost FUCKING LOADS OF TIME!!!)
Plus the extra hotel nights, but all in all after having heard the ferry is sold out for foot passengers until wednesday and no sign of airports opening any time soon, I am gone get on the train have a beer and pat myself on the back.
Well done! Major adventure...
