You have always had to pay to park overnight in the services,lets be honest would you build a service area,spend money building a carpark install lights and then let people park overnight for free, i have always paid to park overnight in any services i have stopped in,in the uk,the cost ie expensive but you do get a meal voucher thrown in in the price.This may sound harsh but its a Bank holiday weekend there is bound to be a lot of traffic on the road it amazes me that people dont allow a lot more time for travelling on the lead up to a bank holiday and also if the time you pulled in was late you wouldnt have got in the show at that time of night anyway,we as a club had people leaving Bristol at rush hour and they still got to the show by 9 all the rest of us took a day off or half a day so we could miss the unstoppable traffic problems that always happen on the m5
