If they carry on with the pattern they used during the test phase back in May, fireworks, parades, and other night time shows will take place at the regularly scheduled times. For instance, IllumiNations will take place at 9 pm, just like it always does, even though the park will be open until 12 midnight for resort guests one day a week. By the way, I'd bet there will be fireworks at the MK on Feb. 2nd, they just haven't listed it on the schedule yet.
These were the attractions open during the Extra Magic Hours test phase in May, 2004. Note, the days are different than the schedule beginning Jan. 2, 2005.
