We drive up there a lot, and Tebay services in Cumbria is fab - play area for kids, duck pond, the wonderful lakes. In terms of routes we never go through London instead going by the north circ onto the M1 that way. Not everyone's cup of tea, but it works for us (through Rotherhithe tunnel, heading for Barking way, then onto M1 when you go past Green lanes). We tend to do M6 as we drive to central Scotland, and so we do the M6 toll. Have done the other route and it is lovely too. Enjoy the drive - the other posters are right - the scenery is beautiful! http://www.westmorland.com/tebay
