I have not met Anna and Elsa, however I have heard very positive things about the meet and greet itself. There is a considerable amount of time spent with each guest, the actresses are very good, etc. I sincerely hope that maintaining this quality of performer/experience is what is preventing them from putting similar meet and greets elsewhere. While I support the idea of reverting back to the old Fastpass system in distribution rules, I don't think the "faux-Fastpass" done in this test solves anything. The solution is for either the demand to die down (it will happen eventually) or to increase capacity. I hope that the only thing restricting that capacity increase is a lack of available candidates to play Anna and Elsa. At something like Fairytale Hall (two devoted rooms), I'm not sure how many pairs of Anna and Elsa's they need to satisfy just that location. I don't know if those characters are also in the parade at MK and/or the summer festivities at DHS. Assuming they are able to hire the necessary actresses, I could see them putting Anna and Elsa back in Norway, in the Animation Courtyard and at multiple dining locations.
