Got MCC Reserve Seat plus vistor pass, had the whole office onto it for me.
Found that the mobile was quicker then the desktop.
I started queuing at 11:45 on the dot, and my colleague at 11:46 and another at 11:47, they both go in before me. Was able to select my ticket at 11:58, and then waited 2 mintues before i confirmed, got an error message, then tried again and purchased my tickets at 12:00pm exactly.
After it was all done, my phone and browser was still in the queue and at 12:08 it got through. Weird how I was first in the queue but my work colleagues got in before i did. Glad I had a team working on it for me.
FYI make sure you are using mobile data and not wifi as the IP addresses will be different.
