We're travelling down to Newquay next Thursday 21st June, setting off at teatime we will get to Avon Mouth on the M5 between 10.30pm and 11.00pm. We are then going to stopover in a motorway services for the first time before completing our journey the next
day. Of all the service on the M5 after Avon Mouth which is the best to stop at?
