I will say, any time you have thousands of people trying for limited tickets all in the same instant, no system is going to run perfectly. The queue definitely gave me heart palpitations, but better than a server going down, or orders freezing, etc, that I've seen previously.
I managed to get two tickets for the dress rehearsal as well as two tickets for Friday. Normally I'd do three or four shows, but making a vacation (possibly honeymoon) out of this with the wife. That said she's only going to the Friday show, so if anyone wants it, I'll put the offer out here first.
For 200 Euro (that's 25 Euro off of full price) you will get rehearsal entry and all the goodies EXCEPT early entry on Friday. Plan is I'll do the dress rehearsal myself and go in with whoever buys the extra ticket. Then I use the two special wristbands to get myself and the wife in early on Friday. From there I can give you the wristband to use Saturday/Sunday for any of those shows if you intend to go.
