P.S, after seeing the news about the tunnel this morning I might go a different way.
Should be alright on the tunnel Stever1. I'm booked on a train on the 29th and not too concerned. Even when STACK is in operation, it can be avoided and the troubles don't appear to be troubling bikers. There is some good info for alternative routes on here by Giles and others. Leave a bit of extra time and seems like it should be fine.
