Gosh, Brier Rose, that's terrible.
Did you try to explain the sitch to the CM's who closed off the lights to the public? I can only say that never say never and my hopes are that your grandmother and grandfather get to enjoy another trip to WDW.
I've decided that we'll try to see the lights after Fantasmic but if that doesn't work out, we'll hop over there a couple of days later after we get kicked out of the MK (it's
MVMCP that night so we'll get kicked at 6pm). We'll probably finish MK early anyway so we can hop over there, maybe have some dinner at Prime Time or Sci-FI (we'll try to be walk-ins and try our luck).
