2 dcs, aged 2 and 3.10, cannot seem to last more than 2 hours before we have to stop for at least 30 mins, thus adding another 1.5 to 2 hours to any journey. going back to same place in south Devon for first time and want to avoid it taking 7 blinkin hours!
had an idea we could stop somewhere on Thursday night but where off the m4? won't be able to pick dh up from work until 6 and will leave via a40,
have suggested the idea of early rising to dh but he did this face 
we can't check in until 3 but are staying practically on the beach so can happily while away a few hours, rain or shine would also be nice not to have to rush around like a blue address arsed fly!
any wise ideas my lovely MNers?
