Screwed up UCAS application?

I'm getting really worried now.
I applied for the initial five options but got declined by the one option I really wanted to go to. 2 have made me an offer and 2 haven't replied yet.
The 2 that have made me an offer don't really appeal to me any more.
I have since seen 3 Unis that I would like to apply to through UCAS extra but I haven't been to any of their open days so don't know what they are like.
I live in Cornwall and all of the universities are really far away so it is difficult and expensive to get to them to have a look around, but I'm guessing I should look around them before I apply?
Because it's UCAS extra I can only apply to one at a time and I'm beginning to really worry about what I should do.

Has anyone got any advice how I can make the best out of a seemingly bad situation?

The universities I'm interested in are Salford, Anglia Ruskin and Glyndwr in Wales. Although Glyndwr has already accepted me from my initial application.

Yeah I know that's why I want to visit Glyndwr first. Although after looking at the website and understanding it a bit better it doesn't particularly appeal.

I'm not sure whether I should apply to another one through extra before visiting it, and then visit it if they accept me or not. Or visit and then make a decision about applying.
