UK - England, Scotland, Ireland/European Adventure - Group Travel

Hi! I'm a 20 year old student from Ontario, Canada, and I'm hoping to have an adventure this summer! I'm looking to find people who I can travel with that are around my age and have travelling experience. This trip would be my very first vacation and I'm hoping to have the best time in Europe. I'm looking to have a good time on the trip and also explore the pubs, clubs, shops and sights. I would really love to find someone who has a lot of expertise when it comes to hostels and hotels in some of the European countries.
I want to spend as much time in the UK before setting out and exploring the rest of Europe. My main focus is immersing myself in the culture of England, Scotland and Ireland. If some people only want to stay a short amount of time with me in some countries than that's fine. I'm just looking to have some companions I can travel with, since it is my first time and my friends from home don't have the money to go out and travel. The dates are super flexible, I just want to make sure I get this in during the 2012 summer. If you feel like this is the sort of trip you would like to go on than let me know :)
