Update - 27/10/16
OK so looks like you can't really block book 10 or so tickets on the site - however I just booked mine and got Block 204 Row K seat 9 - just behind Emily and Paul (see comments below) - so I think if you book round about now you'll prob end up nearby!!
This looks so cheesy it might just be fun - we will def be picking tier tickets as the floor tickets are at a price reserved for the seriously overindulged offspring of time poor money rich parents ... http://www.manchestereveningnews.co.uk/whats-on/family-kids-news/marvel-universe-live-tickets-manchester-10942152
We'll block book this one once have an idea of numbers - cut off point Oct 2015
