So my sister and I will be at Disney the end of August. The one morning we will be doing EMH at Magic Kingdom.. The first ride we will be doing is 7 dwarfs mine train (obviously).. My question is after we ride the mine train, do we shoot over to Space Mountain and ride that or head over to frontierland before it opens by 9 so we can hit the other big rides? Will we be cutting it too close if we ride space mountain?
