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.
last time we were in the foyer waiting to go in, suspended from the ceiling was the magical flying Ford Anglia. This time there was a dragon!
This of course is a model of the dragon that was chained in the vaults in Gringotts.
