I went into Harringtons with my birthday sticker from County Hall last year and the CM who served me asked whether I had had my "phonecall" - when I said I hadn't she rang someone to get a code to put into her phone and passed it to me and it was indeed the "big M" himself wishing me happy birthday!
Hmm.... no "first DLP visit" buttons, eh? Perhaps I'll just make up some stickers that say that, then - not expecting any pixie dust like at WDW, but just to let people know we're newbies!
