It was great for us. It is on the FW side on the lagoon between the 2 shops. We got there 15 minutes before the show and easily got a front row spot on the rail. It was a food and wine Saturday night (Oct. 5) so the park was crowded, but there were not that many people in the FP+ area. We loved it.
That said, I would not have been happy if that area was packed in like sardines. I've heard there have been nights it was crowded in there and people that got there long before we did our night were several rows back from the rail and couldn't see. It is not seated- everyone stands for the show. Everyone pretty much sits on the ground until the show starts though.
So...I guess it is a matter of luck and/or how many people do FP+ for it that night, or how many WDW decides it is going to make available.
