Haha, I did that too! I remember at the last Coldplay concert I went to, me and my best friend were talking to these two guys all day and I finally asked them if they were on coldplaying lol one of them was, but yes, it was still kind of awkward LOL.
I loved your t-shirt idea! I showed it to my best friend too and she loves it also(she's on coldplaying too, but doesn't post much) So we are gonna use your template if that's okay! I don't know if everyone will agree on the same shirt, but as long as everyone does a coldplaying shirt... it will be awesome!
I've seen them 8 times and this will be my 9th time seeing them. They are the only band I have ever seen in concert this much! haha. I am nervous about the festival because I have only ever seen them at their own concerts and although I have seen them general admission before, the festival experience is going to be completely different!
How much do you want to spend? Try expedia and put in westminster. That's a pretty safe area and close to stuff. I am staying at the Holiday Inn Express Victoria. There are several budget hotels on Belgrave Road. None are anything fancy, but the area is safe and I can help you vnavigate.
