Since it's not open yet, and we don't know how well either are going to flow and you have time ... I'd just wait a couple months and see how it is all going. Their popularity at MK has gone down, BUT I think many will want to see the house.
Right now A&E have no FP+, but my hope is the building has the structure to add it if need be. Just like the SW characters at DHS have FP+ structure they just didn't need it.
