PDA's banned - so you can concentrate on your children

In light of a project which I have been working on for some years, the story that the UK's largest theme park Alton Towers have decided to ban PDA's so that parents have to concentrate on their children was - a relief! The company will enforce the ban with wardens, who if they find a PDA user will confiscate the item for return when you and your children leave the park.

I actually think - despite all the "reaction to a survey" publicity details - that personally this has more to do with Alton Tower's insurance liability, than the headline of making parents concentrate on their children - but it just seems like a very good and family orientated reason.
