Belfast is a wonderful friendly place. Queens is a super university and the flights can be really quite cheap to Glasgow and last no more than half an hour. I went the other way round many years ago and ended up at Aberdeen uni. I had to get the boat and two trains - it took all day! I left N.I. to avoid sharing a room with my sister as I lived so close to Belfast. The Belfast of today is a fun, lively city with so much to do. You’ll easily make friends. Don’t worry and go for it. I wish my daughter would go to Queens, she’s headed to St Andrews.
