Disney, at least in my book, has a great track record for building great family rides. I fully expect that to continue. I see no reason to go over the edge just yet.
Aren't "kiddie rides" exactly what everyone says DHS is lacking? You think little kids are gonna care if they're "off the shelf"?
I'll caveat that it's all rumor and conjecture at this point, but my money will be that the kiddie rides will be off the shelf and not great family rides.
And you'd be surprised that yes, little kids do care. Those off the shelf kiddie rides have a shelf life of about 2 years, from age 2 - 4. Definitely nowhere near until 10 yo.
My opinion, based on the rumors and on past Disney performance, is that DHS is not getting fantastic, Fantasyland quality rides. I think it'll get watered down, Bugsland quality rides.
The same complaints about needing family friendly rides were pervasive when DCA opened. So they built Bugsland - which is indeed very well themed and has a fun splash play area. But that's it. The rides are a watered down tea cups, a blah bucket ride and bumper cars. The one ride with real Disney potential (Heimlich) is so short you're off almost as soon as you sit down. And yes, my kid did enjoy those rides - when he was a toddler. But by the time was 4 and hit that magic height of 40", any appeal for Bugsland went out the door.
Lest you think it's all about thrill rides for him, it's not. He's 6.5 now and still wants to ride Peter Pan, loves the spookiness of Snow White and Roger Rabbit is still on his top 5 ride list. These are all good to great rides with originality. Off the shelf kiddie rides are not and even he figured that out.
And it's not just my kid. Walk through Bugsland anytime of day and except maybe the most peak days of the year, they'll all be walk on to 10 minute waits. Heck, regularly you see the rides sitting idle. Because even if they're not tall enough for any of the rides there, the kids want to be in Carsland. 'Cause it's interesting.
I hope DHS gets a better Bugsland. But I wouldn't count on it.
