Perhaps DL management has gotten the idea that DL is becoming a hangout rather than a destination resort and doesn't want it to become another Magic Mountain?
I think this is a good idea. It's easy to believe that with APs being what they are, DL has indeed become somewhat of a babysitting service.
True enough, patents can still take their kids to DL and leave, but the inconvenience of having to park, walk or take the trams to DL, wait in line to get in, etc. has very likely made it no longer feasible.
I don't often agree with the corporate decisions made by TDC, but this one makes a lot of sense.
