"I don't know if I can answer you here in the comments or if I need to make a post, I haven't quite understood.

Anyway, for question 1, you could say Cardiff because you're Welsh, but actually, you mentioned Deadpool, and if I'm not mistaken, that film was shot in the caves of Hertfordshire in England, so I might think you left from Luton Airport. However, there are also other airports nearby.

For question 2, I can confidently say Malaga, because the cube is very famous and has been towering over the Andalusian city's port for several years, and Malaga is famous worldwide for street art.

For question 3, you could say Marracash or Morocco, even though your initial statements about gladiators and mummies made me think of Italy. But then, 'The Man Who Knew Too Much' is an Alfred Hitchcock film, if I'm not mistaken, a rather old film that was shot in Marrakech at the beginning. So, in my opinion, you're going to Morocco.

I must say, this quiz story is very fun."
