The first time I went to the Warner Brothers Harry Potter Studio Tour was in 2015, just after they had added the Hogwarts Express and Kings Cross set to the tour. At the end of November 2019 we made a return visit, mainly to see how different it was dressed for Christmas and with snow.
“It was lit by thousands and thousands of candles that were floating in midair over four long tables, where the rest of the students were sitting. These tables were laid with glittering golden plates and goblets. At the top of the hall was another long table where the teachers were sitting… The hundreds of faces staring at them looked like pale lanterns in the flickering candlelight… Harry looked upward and saw a velvety black ceiling dotted with stars… It was hard to believe there was a ceiling there at all, and that the Great Hall didn’t simply open on to the heaven.”
