So, how was the closing ceremony 'live'? I enjoyed it on television!
My mother also had an amazing time at the Olympic athletics she went to, her sister was in a wheelchair and they said the support from the volunteers was fantastic, things like switching her ticket for one that was more easily accessible without any issues, as was the queue jumping (she told me there was a 2 hour line to get into the large store - they got to go straight in fortunately). Hopefully you experienced similar assistance with the children.
