We were just there last week. Probably considered a slow time. Let me just first say, WOW, what an awesome show. Disney has got it mastered.
Okay, we had blue FPs, and due to circumstances, couldn't get there until 50 minutes before hand. At that point, there were zero rail spots in the main viewing area. But standing down there, I looked up and saw the bridge. I said to the wife, "Maybe we ought to give that a try", seeing as how we have a DD5 and DD3. A CM overheard us and said, "The bridge is my favorite spot.". So up we went.
When we got up there, there were still no rail spots until right under the Paradise Pier sign in a little nook between the rope and the bridge abutment. Well, for our family of four plus my gma & gpa, this little nook was perfect. It was easy to hold, and the nice CM guarding that corner would let us in and out thru the rope as long as one adult stayed, so the kids and a couple adults went shopping on the pier and got bubble guns and had a blast while waiting for the show.
The view from up there was just awesome, too. Yeah, you're further away, but I felt like I could soak in the whole thing, and really appreciate the "waves" and effects from up there. We could see all of the projections, and the angle of viewing was actually pretty close to our position - a little to our right.
All in all, a great spot for showing up 50 minutes early. If we get there earlier, I might try to get closer next time, but its a great fall back location if you don't like showing up 90 minutes early.
