Hi there.
As a student ambassador who has been involved in open day events at our university, I feel I can respond to your question.
At previous events, the vast majority of students come to university with their families, but some come with classmates, friends, or alone on their own. It is normal to come to this event with anyone or on your own, with your parents it gives them a chance to find out about the university so they can get to know you, with friends and classmates you can talk about the university together, and by coming on your own it shows that you are already pretty independent.
Lastly, if you want to come to the Open Day on your own but are afraid of being alone, don't worry about it, you can ask for the help of student ambassadors who will accompany you.
