I have no idea what to do. We are in London. Meant to be driving Wednesday morning to Cardiff to my parents house and staying till Boxing Day.
On Boxing Day, we are meant to drive back to London, and the next day, drive to Luton airport for a week's holiday in the sun 
Do you think that a)we should set off for Wales tomorrow and b)if we do, will we get stranded there on Boxing Day and miss our flight?
I can see a situation where we don't get to Wales then our flight is cancelled anyway
