National Rail Enquiries shows, in addition to the half hourly (:17, :47) services from Brighton, a couple of (extra?) trains at 14:12 and 15:11. Better than nothing I suppose, but as you say, doesn't look like being anywhere near enough.
I'm just mightily glad the North is open. At least we won't have to suffer the abysmal catering queues that are highly evident everywhere else in the ground.
Reckon there's a serious undetected bug in that Queue It site. If I were a betting man and career system tester, I'd bet very good money that the stats refer to to every user using Queue It across every Queue It customer site worldwide, as opposed to just the Albion queue it site. Or something...
It says thousands but it's just so much gormless bolleaux. Site whittles that queue right down to very low treble figures in a matter of minutes. Then the queue moves unfeasably fast. You'll be disappointed if you have to wait more than about ten minutes to get to where you want to be.
Tickets bought in the end but far from a smooth process, including the Chrome / re-login with IE issues that others have reported. Oh and the Queue It thing whereby there's only 10 in the queue in front of you and it just sits there and you have to manually open a new window to access the ticket...
