Just back two weeks ago and like another poster stated, all the shops are open during EMH. The kidcot stations are open and there are several restaurants open too.
Because of this, we found EPCOT to be insanely busy for EMH. There is so much to see and do even without a bracelet, that the crowds never really thinned out in the WS until after 11:00. The whole park was a mob-scene in the late afternoon. I don't think we'll be too quick to do EMH at Epcot again.
