Hi there 😊
Congrats on getting unconditional offers - it's an incredible achievement!
I can understand why you're torn with your options after hearing the mixed reviews from current students. But you have to remember that creative courses like Theatre Design can vary and some styles suit other people better.
When deciding what university, the most important factor is the course structure and fit. Are you able to be creative? Are you going to be in studios and design workshops all day - does this learning style suit you? Is the content covered in the degree something you're interested and willing to learn about?
The student expectation can really differ from student to student. For example some people like structure, independence, more creative outlooks etcs. It is about finding why you are interested in Theatre designs and which areas you're passionate about.
It is understandable that you are considering your grandad concerns and it's understandable when the cost of living is rising. However with living in a big city it's about being aware of your surrounding and UAL has support in place for first year students in terms of accommodation. With the cost of living, it is definitely important to budget but there are many ways to manage your finances like student travel discounts, working part time etc.
I hope this helps and good luck with your decision!
