This still isn't a bargain. If you happen to live near one of these parks, the money you save going on a weekday is more than cancelled by having to take a day off work, or not being able to do it at all because the kids are in school.
This is an empty gesture.
Riddle me this .... which will your kid remember... the day you pulled him out of school to go to Disneyland or the day he learned Polynomials ? Yes... next case...
