its incredible....we went in september, the first week was just 'normal' MK, then at the beginning of our second week, we went to MK in the evening for Spectromagic, then back the following morning and it was a completely different place!
Mickey's 'Not So Scary' Halloween Party was actually a little scary, had a massive thunderstorm meaning the 9pm fireworks were cancelled, but they were well worth waiting till 11:30 for the 2nd show.
Check out my new pic, it was taken that night, it looks like daylight as I managed to take a pic of Cinderella's Castle just as lightning struck!
