I think some parents with young kids were using the accessible queue when I was there on Wed. If that carried on, might be one of the reasons the accessible queue has closed
I didn’t see any pushchairs in the ‘main’ queue but a few older kids - there are stairs but honestly 2 very small sets (like 10 steps in total)
Personally, I think there should have been different arrangements which prioritise those with medical needs (in the way that Blue Badge spaces are not used as parent & child parking etc), & then potentially arrangements for younger kids (but it’s not really a child centric activity, so not a priority vs the needs of mobility impaired etc)
