Don't bother to see it from behind, it's not even the same show from behind. Best suggestion is to have your CRT dinner and then come out and get a good spot on tomorrowland bridge, preferably right under tinkerbell's flight path (look for the wire coming out of the castle going towards tomorrowland). Give yourself a good 1-1 1/2 hrs for dinner before wishes. As long as your in front of the castle, any spot is pretty good but it's just more fun to be under tinkerbell and get a good view and a picture too!
