My friend was at CRT today and had Cinderella (greeting), Snow White, Ariel, Aurora, and Jasmine. It seems like Jasmine is occasionally rotated with Rapunzel and Merida. Akershus is usually more consistent, with Belle (greeting) and Snow, Aurora, Ariel, and Cinderella rotating. Mulan is a substitute.
Besides character meals, you can meet Cindy, Aurora, Rapunzel, and Tiana at Fairytale Hall; Snow White near Town Hall, and Jasmine (with Aladdin) near the Magic Carpets. In Epcot, you can find Anna & Elsa in Norway, Mulan in China, Snow White in Germany, Jasmine (and Aladdin) in Morocco, and Belle and Aurora in France. Pocahantas is the only princess in AK. We also had Mulan, Pocahantas, and Jasmine (with Aladdin) appear at CharacterPalooza in HS. If you care about Disney Jr, Princess Sofia is also in HS.
