On the most recent vlog she shows her ticket...they have Encore Seats.
And what an absolutely boring vlog... walking through hotel corridor.. standing in queue to get in O2, and Uber journey back to the station.. why does she bother.
When I bought VIP tickets at the Greenwich 02 I didn't really understand what they were. It wasn't until the band came on and everybody stood up, so I would spend all evening looking at the back of a tall man in front of me, and the awful jobsworth staff wouldn't lef me stand slightly in the aisle to have a better view, that I realised I would have had a better view somewhere else. Also you have a pressure to keep dancing and I hate dancing, but would look stupid with not dancing as you can't sit down. Their view of Little Mix looks too good to be the standing area at the front, as you're looking up, but they were looking down.
I thought was unusual to get a taxi, as there's an underground station a few meters from the 02 entrance.
