I’ve actually seen a gaggle (is that the correct term?) or disablders at x-scape – they have a ‘wheelchair’ ski thing which is controlled by a skier behind them. Not sure how many were parked in the car park, however.
I generally don’t use any restricted spaces, though would have no worries using a parent etc space. Unfortunately many blue badges are abused – and further, are only for permanent disabilities – so when I was going around on crutches with what I later worked out was probably cracked ribs (started to get serious chest pains with any decent amount of crutching) I wasn’t allowed to park in them – still did in some cases, usually getting a few dirty looks in my sportyish looking car, until I clambered out with the crutches.
