How useful do people find open days? I want to start thinking about university early and wonder how many I should go to.

Are there any questions I should ask on tours and stuff? How do people get there as well?

I didn't go until really late - not until id made my 6 ucas choices! Not sure it was the right thing to do, but still helped a lot going. didn't really ask question but it helps to get the feel for the place.

I would say it helped me narrow down my choices well - in the end I went to the uni where I felt most comforatable at the open day.

opendays.com has a section about questions to ask http://www.opendays.com/advice/advice_ques.htm though it didn't really help me
