Travelling by car from Manchester to Devon with little ones

[kellibabylove]

Were making the 6ish hour trip with our 2.5 & 3.5 year old dds next Saturday. Were leaving at 3.30am. I need suggestions on the best services for breakfast ideally with a play area and the best things to take in the car for comfort and amusement. Also how many times would it be advisable to stop during the trip.

Hopefully most of the journey will be covered with them still sleeping.
Take light snacks bananas and 'puff' style snacks and cold juice and just stop as little as you can get away with,in my experience travel with small children is best done as quickly as possible .

See the alternatives to motorway services thread for places to stop
