I don't think they quite make it to Spring Break...
[FONT=Verdana, Arial, Helvetica, sans-serif]Party nights: Jan. 22, 26, 29, Feb. 1, 5 ,8, 12, 15, 23, 26 and March 2, 5, 8. from 7:30 p.m. -12:30 a.m.
I wouldn't compare P&P extra time to EMH extra time. P&P was a lot less crowded than I've ever experienced with EMH [particularly in the first hour of EMH, when the lines for rides seemed as long as during the day].[/FONT] I didn't see the new parade, but DS and I aren't really into parades anyway. The P&P fireworks were worth the price of admission alone!
From what you say, you likely wouldn't buy tickets regardless. If it is still on when you're there, just avoid MK the days it's on, there will probably be EMH in a different park..
