So... We had our Harry Potter day, and got the girls to hand the tickets to the crew member on the loading part of the platform just prior to boarding the train. We didn’t give the crew member the heads up ourselves, we just let the kids get on with it themselves.
He’d obviously not had this done before, but he ‘sort of’ went along with it, although I don’t think that he was a particularly jovial-type anyway (a bit like myself.lol)
So far, so good... However, he came onto the train before the doors to the carriage closed to return us the tickets, as I’m guessing that he must have thought that we wanted them back. We overcame this by telling the kids that he’d just stamped the tickets, and that he knew the ‘secret’ that they were now wizards, as they were in Gryffindor Robes with wands in-hand that they’d bought that morning from Ollivander’s with their Harry Potter money.
It didn’t go exactly as I’d expected, but the kids weren’t any wiser, so all in all, it was worth doing. I took some photo’s, but obviously wouldn’t post them anywhere as they’ve also got the crew member on them. We had a great day, but the Florida heat was brutal, so had to bail out early, but we came back later to watch the light show on the castle, which I thought was fantastic!
Thanks again to all who replied!
