Absolutely YES!!!
We are actually planning a whole trip just for this event. The parade is worth the price of admission. And if you have hopper passes you do NOT have to use one of your days for admission into the event. You get 5 hours in the park with mostly all the rides open(substantially more than e-ride nights) . The cost for adults is $34.00 with tax ...alot less than a 1 day admission ticket. And beside the great parade, scary and not-so-scary story telling in an intimate setting and a DJ with NON-disney music over by Buzz you also get UNLIMITED candy...they even provide the trick-or-treat bag. My kids and I loved it!!!!!
