Sally is one of the company directors and manages the Kickstart office enabling the rest of us to enjoy ourselves instructing. You can trust Sally to recommend the best course for you, if 3 days are sufficient for your training then she will not try to sell you an unnecessary fourth day.
If you require advice regarding Licence issues (e.g. foreign, EU, disqualification etc.), then Sally can normally advise you straight away about what you need to do, and if not then she will quickly find out for you.
