Here are three pictures. Your task is:

a) Guess the city. That should be the easy part.

b) Tell me what they all have in common. (Aside from the obvious, ex: they are all located on an ocean)

I like Marcanadian's answer: ABC...I never wouldve thought of that, but thats wrong, sorry
dizflip is also wrong, though that is true...

They're all on the East coast of their countries?

...thats not what I was thinking either...damn I didnt realize they had that much in common.

their countries are the biggest of their continents?

also true...damn...ok...one more guess and if they dont get it I'm giving it to Marcanadian, because he was the first one to guess something intriguing.

that they're all in the South East of their countries??? That they're the most touristy city of their province???
