I think this is really poor and it seems to happen a lot. Apparently staff said they would give it another 10 minutes and then it would be abandoned and they'd all have to rebook. Luckily it then got resolved, but ds said people were getting a bit panicky and one girl in particular was getting more and more distressed during the wait and another had travelled nearly two hours so not that simple to arrange another visit. DS says he wasn't bothered by it but for those who are it seems so unfair and surely it should be avoidable. It seems to happen every year to one extent or another.
