Wishes! is totally worth it and should not be missed. If you're going to break your stake-out rule for something, have it be Wishes.
Regarding EMH:
We don't do AM magic hours ever. We get to the parks whenever we can, sometimes RD, sometimes not. On the other hand, we try to hit every PM extra magic hours, but typically start at a different park. For example, this May we'll spend most of our day at Epcot then hop to Studios for PM EMH.
