[Troubled Waters]

So maybe I have left this a bit late to find out but...
We are going to see U2 on Saturday (wooo and indeed hooo!!!) and are driving.  I know there is no parking at the Stadium so just wondered if anyone else has been to events there and can offer suggestions??

I have read there is often a park and ride (long queues for busses after) laid on and well sign posted but can see no info about it.  Also founf www.stadiumparks.co.uk offereing parking for £14 but not sure how legit they are.

Many thanks peeps.
