I'll be there, but leave before you get there.
We fly AA J to DUB on 9/16. Spend a couple days there visiting family. Then we fly to Berlin on Ryanair, spend a couple days there. Take the train to Heidelberg, spend a night there. Then four nights in Munich for the 'fest.
I used points for pretty much everything. We got three nights in the Four Points at Olympiapark using SPG points.
