AG is set up differently than most character meals. They have a short range of time they seat guests (so everyone doesn't show up at once), then as the last group is getting seated they start announcing princesses one at a time. There is a span of a few minutes between their entrances so they can visit a few tables before the next one arrives. They go table to table throughout the room in a certain order. It's not like Goofys where people are constantly coming and going and characters rotate in and out in between.
