The Magic formula

This weekend, Edinburgh's Murrayfield Stadium will play host to Rugby League's 'Magic' tournament, which will see fourteen teams play each other in seven matches over two days....and all at the same venue. In event management terms, is this a recipe for disaster or success? One would assume that the benefits of hosting such an event for a city like Edinburgh will be significant; what is likely to be the overall economic and commercial impact of the 'Murrayfield Magic' days? And are such benefits likely to be sufficient to prompt other cities in the future to compete with Edinburgh (and former host city, Cardiff) for the right to host the event? Will the event actually deliver a net economic benefit to the city and to the event's organisers? Or will event costs outweigh the benefits, yielding a net economic loss? After all, organising and managing the event must constitute a logistical nightmare? How will crowds be managed? How will the pitch be maintained? How can security be ensured? Won't hotel accommodation be at a premium? Surely there will be problems with congestion? Won't there be diminishing returns associated with the event's benefits and disproportionately higher economic costs? Or, in reality, is Edinburgh actually a great and economically justifiable venue, as the city has hosted such 'mega' events before?
