Thank you all for coming to my talk this evening. It’ s nice to see so many people in the audience. For those of you who don’ t know very much about PS Camping, let me start by giving you some background information about the company.
    The company started 25 years ago. It actually opened as a retail chain selling camping equipment, and then twenty years ago, it bought a small number of campsites in the UK, and began offering camping holidays. The company grew rapidly and has been providing holidays in continental Europe for the last fifteen years.
    If you book a camping holiday with us, you’ll have a choice of over three hundred sites. In Italy we now have some 64 sites that we either own, or have exclusive use of. France is where we have the majority of sites, and we currently have a project to expand into Switzerland. We also have a number of sites in Northern Spain, particularly in the mountainous region of Picos de Europa. We’ve upgraded all these Spanish sites, and improved them considerably from their original three-star rating.
    We believe our holidays offer superb facilities for the whole family. Parents who want their children to be fully occupied for all or part of the day can take advantage of our children’ s activities. These are organized by our well-qualified and enthusiastic staff. Each day kicks off with a sports match, perhaps football, or volleyball, followed by an hour of drama for everyone. This may include singing or dancing, mime or other activities. In the afternoon, there’ s a different art activity for each day of the week including a poster competition or model making. What’ s more, our sites are truly child-friendly, and, with this in mind, we operate a no-noise rule in the evenings. Children’ s evening activities usually finish at 9:30, or occasionally 10, and from 10:30 holiday-makers are expected to be quiet in the areas where there are tents.
