Thanks, guys, for the nice feedback :-)
MLind - The reason I return home in between DF and EE, is because it's to difficult for my wife to take care of our 3 little girls for so long, when she is alone.
Thus, it is unfair that she carries all the burden by herself in that period of time, while I am having fun with you orcs
So the 5 days in which I will be back home, will help her a lot, and allow her a little bit of "air".
Had DF and EE been one after another, with no "window" in between, I could have stayed for 2 weeks in a row in Germany.
However, fact is, there is COM in the middle (which is not to my taste), and it makes it 3 weeks altogether - which is too long for her to stay alone with the girls.
Maybe in 2019, (when the baby will be almost 3 years old and much easier to take care of), they will all come to visit me after DF and we will make a trip in the week between the cons, and when they fly back home I will continue to EE.
That way I won't have to fly back and forth, and the family will also have some fun :-)
