Re: the whole Shambhala being a family attraction thing...
In my opinion, it is.
Well, family is possibly the wrong term. Like someone else mentioned, "family attractions" are not just things people of all ages can physically go on, but things that appeal to a wide age range in some aspect, including if they were to sit out the ride. Rides which appeal to non-riders are awesome.
It WILL be tame. It's a B&M hyper. They are ALL tame. Okay? It's going to be tame.
But stepping off the enthusiast pedestal for a moment... This thing has a tame sounding name and colours. It's not meant to invoke thrill or fear, they have chosen to make it seem calming, magical, mystical. Those aren't "family" things necessarily, but it does make it accessible to the family audience.
It's not an alien concept to present 1.4m rides as "family" attractions. Alton's Air and everything at BGW are great examples. If a 205ft vertical drop coaster painted wonderfully unintimidating baby blue doesn't convince you of the sense I speak, nothing will. 1.4m tall kids are hardly too old to be part of the "family" unit. People need to stop thinking that everyone over 1.4 is an "adult" and likes scary or thrilling or intimidating rides. My mother is 60, she's well over 1.4m tall, but she loves Air and won't go near Nemesis.
So why is it so tall? To keep it interesting for thrill seekers. See, it works both ways, thrill seekers still ride Air because at the end of the day, it's a big roller coaster. The elements that make it accessible to more timid riders don't turn off thrill seekers enough to put them off. With a thrill element, such as height, to regain any interest lost.
And what you're left with is a ride accessible to a wide audience in some way shape or form.
