My main purpose of travel to Schengen region is Tourism and I am going to mention the same in my application. I might also look to meet some friends. However its more like if they have time, we might meet and travel around. Still for transparency purpose, I want to specify that in my application. Does the application requires full details about friends if my main purpose if tourism and trip is fully self sponsored.
As trip is fully sponsored by me, I don't see it necessary but need some inputs on this.
