Meeting Girls In Summer?

I met a girl on holiday on a cruise ship who I hit it off really well. She found out I liked her from another bloke and said she liked me but not in that way. We didn't fall out and kept talking. After we got back from the boat she said she broke up with her boyfriend and really started talking to me with some enthusiam. I found out she lives near Milton Keynes which is only a train journey away and she said 'I could easily get there' and now shes given me her address saying 'u know where i live ;)'. If i go down will I look too desperate but I would like to meet up with her. What do I do to make it obvious I want to meet up but not look desperate.
