UPDATE: "Dear Dream Theater Chester VIP fan,
Harrah’s Chester Downs has assured us that there is
no age restriction and that the Dream Theater show on July 21, 2012 is an all ages event. You no longer need to worry about refunds, as all guests will be able to attend, regardless of age.
No further action is needed on your part and all of your tickets are in good standing and still valid.
Thank you and we apologize for the confusion"
So there you go kiddies, no need to worry.
