Leaving DS to look after his own finances here too. His maintenance loan will cover his rent plus leave a little left over per term. We will pay top-up maintenance money into his account monthly (but not over the summer months) to live on. He has done nothing with his small allowance he's had from us in recent years to indicate that he's going to go totally mad. He is quite sensible.
I do agree that even as a full fledged adult, I would probably be a little quiet and unenthusiastic at this stage, put in their position. It is a massive thing. So many new things to be dealing with all at once.
I am just pleased that there's quite a posse from DS's school going to his university even though they're not local to it. Not a whole, established friendship group but their secondary school is small enough for them to all know each other reasonably.
