First off I would like to say I am getting too far into this already... These blueprints excite me so I am probably setting myself up for disappointment in the long run
I am a 25 year old male with no kids and I absolutely love this concept. Disneyworld is an endlessly evolving place and changes like this are welcome. It has been quite some time since they shook things up a bit and this looks to be great.
It may be more geared towards girls, but as others have said there are plenty of boyish rides in the park. If a parent cannot get their kids to compromise and do something that their sister wants to do then you need to work on your family values a little bit. I remember when I was a kid I would have to tough out some of the less desirable attractions for my younger sisters, and went in with the attitude that I would get to see them happy in the end.
I have always said that the Magic Kingdom doesn't have a truly good restaurant that is well themed (haven't been to CRT until this upcoming August!) and usually end up taking the monorail over to Epcot to dine somewhere within the World Showcase on MK days. That being said, the 'Be our guest' restaurant really intrigues me and might be my favorite part of this blueprint.
One thing that always drives me towards Disney over other parks, despite my love for thrill rides, is the extreme care put into theming. The dark rides at Disney beat out even the best rollercoasters that I have been on (and love). I welcome new ones like the Little Mermaid and possible other princess themed ones! Don't forget that puts more people in these lines, which in turn will lower the other lines slightly. This goes for the M & G's as well. Ariel's Grotto currently has long lines, but if all 5-6 princesses + Tink all had M & G's in the same area in separate lines, each of these would be shorter than one superline. I don't know about you, but I would rather spend 15 minutes in line to meet one princess than an hour to meet 4. That way you could see one, maybe take a break from the lines and do something else, then hit up another one later!
Lastly, my wife is a HUGE fairy/princess fan, and seeing her experience this area would be marvelous.
Life is too short to get angry about changes that aren't even confirmed, its much better to spend that time getting excited about them. Get rid of that negativity and life will be more enjoyable
Put trust in Disney! No matter what they do with this area you know it will be done with great care and you know it will end up looking GREAT!!!! Keep the speculations going though, as this entire topic has been a fun read
