Just wondering what people's thoughts and experience is of various marketing concessions to entice extra visitors and receipts. Looking across various railway centres and competing heritage museums and attractions there seem to be a wide variety of different ideas about entry discounts e.g.: child and family ticket discounts which vary on ordinary days from a free child with each adult ticket (e.g. Ffestiniog) to small discounts relative to the adult price (e.g. 20% at Didcot) , reductions for society members, heritage railway or BR staff passes (some societies such as the Ffestiniog and Talyllyn being particularly generous with free travel and others such as Bluebell recently deciding to include BR passes), local resident concessions, and, 12 months free return entry as part of Gift Aid arrangements e.g. Beamish and Crich Does anyone know of sources of analysis of the effectiveness of different pricing and discounts in boosting overall visitor numbers and the commercial benefits of the various ideas (e.g. additional shop and cafe sales from 12 month entry or simply tipping the balance of a visit because of the perceived added value from the 12 month offer)?.
