Interviewing people and collecting opinions

A couple of days ago I had the chance to "interview" some of the people in my class about my project. I have been asking random questions such as: would you be interested in going to Milan? Why? What would you do? What would you like to do? What do you think about it?
In order to get a fair judgement and to really get an idea of what to include in my guide and how to structure I interviewed both boys and girls but mainly people who had never been in Milan before.
Here is what came out:

• People know really really little about the city
• The main thing that they were interested in was the "Duomo" which is the symbol of Milan. I found that quite disappointing. 
• However, they all knew about Milan being quite a fashion centred city. Some of them were also interested in shopping. 
• Mainly the boys were interested in Italian Football and Football clubs so they were asking about San Siro. 
• They all mentioned eating good Italian food but they did not specify if they would like something more specific to be included. 
• There was not much interest shown for the history. This helped me to decide that I need to find a way to turn the history of the city into something fun! 
• A couple of people specified that if they will ever go to Milan during summer they would definitely go to the lake. 
• Overall they were all thinking about the kind of holiday when you don't do much and just walk around and see if you are interested in something. I don't know if this will be good or bad for my travel guide.
