Uni doubts post results day

Hello people,
This year I visited Warwick Uni and quite liked the campus. I also know of some other people who were going so decided to firm the uni even though I changed the course I originally wanted to do (which was fine). I also knew it was high on the rankings which also made me more inclined. As I did more research I found the Uni of Leeds a lot more appealing in its course content and as I didn't think I would get into warwick. I had a strong idea I might get into leeds so gradually became more excited about going there (I do enjoy the idea of good nightlife and just more of a sociable environment) although I had never actually seen the uni itself and saw most of this through social media. When results day came around I ended up getting into warwick and was initially very excited as I got into what I would consider a prestigious uni. Although, as I have done more research I am worrying I wont enjoy it there. I have heard that there is nothing around in terms of nightlife and just social things to do and I am more inclined to believe that most of the people that go there are more lowkey and are not really party people. Now, I have left it too long so there is no longer the opportunity to switch uni’s/ go through clearing. But I just don't know if I am overthinking it/ or am being silly for thinking I shouldn’t even go. Everyone has told me I would enjoy the uni atmosphere but I’m just not sure Warwick can give that to me.
I would appreciate some words of wisdom from anybody who was doubtful before they went to uni or just anybody who thinks they can help with my situation. Sorry for the ramble!
