Fishgurad to London

[user1465302985]

Hi, we will be driving from Fishguard to London with two children under 5 this summer. Does anyone know of any motorway stops which have childrens play areas in them or maybe some just off the M4? Cheers

Ooof - feel your pain. That's a long journey. Whereabouts in London are you heading for? (It could take 2 hours to cross from side to side.) Train would be more pleasant.
There's a McDonalds off J47 with a softplay.
