Nope. You'll love it. Go enjoy all the stuff that Magic Kingdom has that DL doesn't. Enjoy a Peoplemover, COP, and Country Bears. Check out the improved HM. They're different, but both highly enjoyable. And even though most here might dislike the NEW Tiki Room, check it out for yourself.
I used to be able to go to both parks each year and really looked forward to the differences. And it is REALLY nice that they actually HAVE a night time parade in the MK. It still burns me up that DL doesn't.
What's really great is there are enough differences to make them almost like a new park for you.
The Electrical Parade is at DCA.
