Unfortunately the Euro organisers rely heavily on volunteers to steward, photograph, layout the hall, etc, etc. As the show is now run by an organisation for profit the prospect of them hiring security or glass cabinets for the event I imagine is pretty well zero. Remember that events like Girona receive a heavy subsidy from the local tourist board, I very much doubt that this is true at Folkestone. From my days of exhibiting at the NEC I can tell you that cabinet hire for the event would be in the region of £250+ per cabinet. I notice that they do have a couple of cabinets for the Judges display. BOS etc so they will be well aware of the costs. One negative of using cabinets is the reflection making photography difficult.
My own view is that they should ban photography, photograph each exhibit and sell a DVD/CD of the pictures with the magazine later in the year.
