there who either don't want to be there or have an attention span of about 30 seconds and everyone on the row has to stand up 4 or 5 times in the half for the kid and parent to get out an back in or they start kicking the seat in front of them etc.

Many kids do great at games and I love seeing their excitement and fascination for things around. Others have a hard time though and should either be left home or closely monitored by parents.
