It looks like as soon after I got off they started loading full rows or rows of three. Didn't get more staff on as far as I'm aware though, such a slow moving queue.
Tried it as air again today for the first time since the retheme. We were put on the front row and my headset smelt really bad, so I thought I might as well just do air. It's really weird being the only person without a headset on, you can see the people below you watching you, and I even saw two pheasants sat right below the track. Portal looks nice from on the ride, especially on the front row.
No idea what they were doing this morning though. Staff looked clueless, putting one pair per row and splitting up any larger groups. Didn't look like anything to do with the vr, since the staff weren't telling people which seats to sit in.moved painfully slowly though in the queue.
