Walking into Changi Airport was like casting the spell Dissendium. Harry, Fred, George and the Marauders have all used this spell to gain access to the secret passageway from Hogwarts to the cellar in Honeydukes. Standing in the middle of Hogsmeade, it felt as if I had done the same.
Despite wanting to obliviate my memories of being sick on the trip, the ending was worth the suffering. This is quite possibly as close to an actual wizarding world as I would be able to experience in my life.
You can also buy exclusive Harry Potter and Fantastic Beasts merchandise at a booth in the Terminal 3 Departure Hall. It was definitely worth arriving at the airport early for.
