Wishes Dessert Party... when to line up?

We got a last second Tomorrowland Terrace Dessert Party reservation for Sunday. The reservation reads as starting at 9:20pm, with Wishes at 10pm. What time do you recommend we show up at?

I know that they set seating with name cards, so it’s not critical to arrive like an hour early, but I wanted to get a sense of what is typically thought of as the best arrival time for this event.


Recent reports are that they are not assigning tables before you are seated. I would be there by 8:45. They will be seating people by 9:00 and the line may be long by 8:45.
