We just came back from our trip, and we watched spectro and wishes twice, so I can give you my advice there, but we didn't see illuminations at EC, so I can't help you there, sorry! The first time we watched SM/Wishes we we're right at the end of Main Street, just past KC hotdog stand but not on the bridge, and it was a great spot, one held the spot with the kids while the other ran for food, or took the kids to sit at the tables at KC's. For Wishes, it is great because you have a good view of all the fireworks and of the castle, since they do some lighting effects with that. The second time, we watched spectro just behind YE OLD CHRISTMAS shoppe(right across from hall of presidents), and that worked out better for the parade, because there are benches back there, but then we had to move for Wishes, that night we watched them from the bridge that connects adventureland to main street, whilee still good seats, not as good as KC's. As far as wait goes, we waited a while, but we had HEAVY crowds, your best bet is to scope out closer to parade time, or take 2 cell phones or those walkie-talkie's with the 2 mi+ range and send a scout up to see if people are gathering, and talk back and forth that way, or just ask a CM they have a good idea of how long in advance people are gathering. Hope this helps!
