I went on one of these courses in March 2011 ..... 36 in a 30 ........ lots of peeps there and it wasn't too bad .... no lectures just explanations of why it's good to stay within the law .... I felt sorry for the guys who had had to travel a long way ..... one from Surrey and one from Durham ....... it has changed the way I drive especially in town.
I'm surprised you didn't have to go back to Wales so that must be considered a bonus
