A strange post or two on this thread. Anyway, OP, I vote Poly main beach all the way. Audio is fantastic (the speakers installed along the way over the last couple of years have really improved conditions), it’s a decently large area so you can move around/shuffle depending on the crowd landscape, it’s the most “direct” view and of the show with the best angle, Barefoot Pool Bar is steps away for a beverage while you wait, or something To Go from Tambu Lounge or Trader Sams Tiki Terrace. Check for Electrical Water Pageant times and you may also be catch that too. A great way to end a Disney day. Nothing wrong at all with other resort viewing places, but IMHO Poly main beach has the best overall package.
