Maybe I'm overestimating the time it takes to pull thongs together, but in the last update I saw about the Emotional Whirlwind, they were just laying conduit. That was maybe a week ago? I mean, I understand that they will basically just drop the re-skinned ride in the spot, but it still seems like it will be a few months...
But I expect it will be open by June, since they will want rides in DCA to be ready for SWGE's opening day to absorb some crowds.
