I believe some European cities have their own rules which means for some shows you will be able to split 2 tickets over 2 nights, but some cities you will have to use the code for one show only. As to which cities allows what, thats not clear yet...
Why hello stranger! A tiny bit of clarity at least. Are we thinking the UK shows are going to wind up being 2 tickets = 1 show?
Oh, and regardless of clearing my history blah blah blah and despite resubbing I can still only see the free general side
