I finally went to DW and rode Expedition Everest and it was way better then I expected.  The first time I was third from the front-absolutely the best place to be when flying backwards in pitch blackness.  The second time I was in the very last seat, of course the best place to be in the second half of the ride and for the drop.  I had seen the POV's, and can tell disney has definitely improved theming and tweaked the ride since they were made.  I got to the park really early and did not have any wait time even though all of Orlando was on spring break.  After the two times though I could not get near the ride without and 1 1/2 hour wait.
