The confusion is over the closing time of Future World. Although the closing time is listed at 7pm, the popular attractions like TT, MS, SE, Soarin', and maybe one or two more, continue operating until 9pm, or the closing time of WS, whichever is later......normally 9pm.
EMH begins at the closing time for WS and continues for three more hours for both WS and FW.
There is probably a list of what is running during the evening EMH on allearsnet.com.
