Having read the arguments on both sides regarding overnight stays on the French 'Aires', what are peoples thoughts on trying to get a few hours sleep on Motorway services this side of the chanel. In summer we will be setting off from Preston after work on a Thursday evening to catch an early to mid morning ferry on Friday. We want to break the journey & stop for a few hours sleep mid way. In years gone by we have just driven through the night but this time we have a longer drive on the other side. We will want to stop late and leave early so a site is not really suitable. Any thoughts, tips or reccomendations?
