WHEN WE RETURNED BACK , ON TIME ! WE WERE TOLD WE OWED £144.00 , THIS CAUSED A LOT OF DISTRESS AS IT WAS 1 AM AND DARK AND DAMP , ANOTHER COUPLE ALSO FOUND THEY OWED OVER £400 , A CHAT WITH YOUR GUY IN THE OFFICE ENSUED AND HE ALLOWED US OUT AFTER CHECKING OUR BOOKING REF NUMBER, WE HOPED THE COUPLE BEHIND ALSO WERE OK , BUT IT WAS A SYSTEM GLITCH AND AS WE KNEW WE WERE ON TIME AND WOULD OWE NOTHING WE WERE QUITE PLEASED , SO A SHAME A GOOD STAR HAD TO BE REPLACED BY A NORMAL ONE , HOWEVER IF WE WOULD HAVE TO PAID THE AMOUNT YOUR SYSTEM CLAIMED WE OWED IT WOULD HAVE BEEN A VERY POOR STAR.THANKS TO THE CHAP IN THE CONTROL ROOM WHO WAS POLITE AND VERY EFFICIENT ,HOPE THE GLITCH IS SORTED AS I AM SURE WE WILL TRY YOUR CAR PARKS AGAIN IN THE FUTURE .
