So if I was to travel America where should I go?

Basically I want to travel America next year.
I live in England and whilst I know that many of you find that interesting I want to see America because there is so much on one continent. So I am asking you…what should I see, where shoul I stay and how much should I pay? Any information would be great! and I would love to go for coffee/tea with a couple of Flutherites along the way. I have a maximum of three months so bear that in mind and advise me! Thank you all ^^
