Once on the ground in Europe travel by train or budget airline is very easy; if you want to do extra travel it is probably better to use the round the world ticket to get from one region to another and then do "local" travel separately. That said, Luleå is 10 hours drive north of Uppsala, which is 6 hours north of where Coronation was held, which is 1 hour from the Copenhagen airport. Therefore I will understand if you don't make it all the way here.

Alas, your travel is too early to attend the Revel in a Rathaus/Academia della Danza down in Germany. (I don't know yet if I will make it, but I had so much fun at it last year, when it was in a castle rather than a 14th Century Dance Hall, I hope I make it there this year, too)
