No one on this board can tell you for certain what will happen to EMH, but it is likely that it will not be available at both parks. I have heard it is going to revert back to DL EMH on T, TH, S, SU and DCA EMH M, T, W.
As an AP holder, I hope this is the case, so I have the opportunity for a non-EMH rope drop for each park during our next trip.
