I did the "new" party in May, we had reservations and they were accepting same day walkups, though it didn't look like they had any takers. We were seated on the rail on the left of the terrace near the buffet, and this is optimal seating in my opinion. We were right at the first bend in the railing as the terrace starts to stick out, if you know what I mean. They originally tried to put else elsewhere but I asked if we could be farther to the center of the castle and they were happy to seat us there. We were the third or fourth family in line. It was a good view and very comfortable, no one stood which in my opinion made it much nicer than the previous dessert party set ups. May I have a picture, I will check my phone.
