Fast Pass for Electric Parade Question

We usually grab a spot in front of the Hall of Presidents. But this time I’m thinking about getting a FP for the Electric Parade and then just staying put for the Wishes and Celebrate Magic. Or will they ask us to move along after the parade ends. We’ll be there in early January and the Parade is at this point scheduled for 7, CM at 7:45 and Wishes at 8. Would this be a bad idea?
