3 days in a Gallardo -Oxford to Bournemouth to Elan Valley

[warwickj]

Hi oh road oracle!

I need your advice on the best routes in the south for my 3 days in Gallardo to celebrate my 40th!
Starting from Oxford I need to go Bournemouth on day one to pick up my son from school as a little suprise! The second day from Bournemouth I need to find the nearest & best driving route, bearing in mind the £2.00 per mile charge on the Lambo hire! I recon the best bet is the Elan Valley area in Wales. After an overnight stop in Wales then back to Oxford.

So any advice on roads between the 3 way-points would be great plus any intelligence on the dreaded cameras also welcome!!
