Well, the thing I don't like, is that indeed these rooms are sold as great "story-telling". See
this post on the Disney Parks Blog. Here they are specifically called "Disney Story Rooms". And my argument would be that they don't tell a story, they showcase elements which are taken from a story, but that is different. Let's take the pirate rooms: if you were to tell the story of being a pirate, the bed would not look like a ship, but would either be a hammock (yes, not very practical in a hotel...
) or maybe a heavily decorated old fashioned bed if you were to stay in the captain quarters. The bed being a ship actually takes you out of the story.
However, I also think that this a larger trend all over Disney that instead of inventing new stories - like travelling on a train in the foothills of Mt Everest and encountering the Yeti - or travelling through a Haunted Mansion encountering various ghosts - they just rely on stories which already have been told before. It is not only the Animation Resort, it is also most of the recent projects - from the Beauty and the Beast restaurant in the FLE to Carsland and Avatarland. This of course has always been part of the parks since the beginning, but not in that exclusivity and scope as it seems to be done today.
I get the feeling that they don't trust their audience anymore to be able to have the fantasy to live inside stories which haven't been played out in detail for them before. And that I think is sad. Where else do you have the possibility to imagine to be in a far away place which might be different for me from the place you imagine to be in because there is the space for our imagination to shape the place?
And to your argument about those rooms only being at the values: Well, the cheapest rate at AoAR is $ 97 for a weekday in value season, in the summer it is $ 139 for the weekday, $ 164 for the weekend, actually $ 5 more expensive than Pop. And the suites at AoAR start at $ 249. Not really cheap accommodation in any case. If you look at the Royal Rooms at POR, those start at $ 189 in Value season. And depending on view/location, in the summer they could cost up to $ 265 for a weekend night. Christmas and Easter would be even more expensive. For the Royal Rooms the premium for the decoration is between $ 30 and $ 40 per night!
