We are going to London for a couple of days in the Easter holidays, will be my DD age 7yo first time. She’s a big Harry Potter fan but isn’t ready for the studios yet as we’ve only watched the first two films and half way through the third book, and she isn’t old enough/ready for the Cursed Child show. I know about the shop at Kings Cross and the half a luggage trolley in the wall there. Just wondering if anyone had any other Harry Potter related recommendations!
