We intentionally went there at 730pm and requested the seats close to the rail but the reception said the seats are already pre-arranged. She checked though in her computer where we are seated and found out we are closed to the rail, I think because we were one of the earliest bookings. We booked it on the first day the April 13th fantasmic package was open.
Just an additional info... all people in the upgraded option were all seated during the show. I did not see anybody went close to the rail to get a better view. The reason could be that All the tables in that package have the good view.... our spot I would say is one of the best spot especially if you have active kids... it’s in the far left side of the terrace close to the rail (in case you want to request it). Enjoy!
