RSR, GOTG, Soarin(? It used to at least, didn't check my last trip), TSMM, Screamin off the top of my head. If you get MP remember to grab your first FP as soon as you scan your ticket into the park as you can pick up FP during EMH for use starting as soon as the park officially opens. (FWIW my top tips for DCA EMH:
-LOVE single rider RSR that time of day
-if a ride is down move onto another, the time is too prescious to spend waiting for something to open
-if you're staying GCH go the front DCA gates through DtD, don't use the hotel entrance to DCA)
Have a great time!!
