Jim, just seen your question on how to get to Birmingham, will you be driving or using public transport?
I have travelled to Amsterdam before from Newcastle via Lomndon with National Express which is a cheap coach travel firm.
You should be able to book an open return journey through them in Amsterdam to Birmingham

Here is another site I have just looked at which may help,

If you are driving here is a link to the AA route planner which is handy, Dover to Birmingham

If you are driving you could travel to Hull by ferry then on to Birmingham which would take an hour less.
Hope this is of some help, Tommy
