This question already has an answer here:
So a friend of mine will come visit soon and he has booked two hotels for his stay in Europe (same country, same city).
These hotels bookings are used to obtain the visa. So the first hotel won't change but we he may cancel the second to find another place to stay once arrived here (A more convenient hotel depending on where we want to spend time, probably closer to my place etc... it is a big city). But we are not sure yet.
Would it be a potential issue for the visa validity if the second hotel was changed once he made it here? (I am thinking of the when the immigration needs to contact him)
