***Edit, Edit, Edit!***
E-ride Nights for March are indeed the 11th and 18th. The information I got today was printed just before the change, and the schedule for the week of the 9th is still being made.
Again, veryveryvery sorry about the inaccurate info that was on this post mere minutes ago.

E-nights have only ever been offered at MK, and they are scheduled based on projected attendance. Some months may have 2 each week, some months may have 1, some months may have none. A month without E-nights is usually regarded by some as an indication that the program has been cancelled, but that is simply not true. SpectroMagic has always been offered on select nights outside of Summer. The next two Saturdays will each have a 7pm performance of that parade.
