Test Track is definitely not a family ride.....
How many of us here have had to sit and wait what seems like forever while doing a child-swap at TT? I've done it multiple times. Its an enjoyable ride...but not one the whole family can enjoy. But really there aren't that many family rides at WDW outside of the MK...just more than are at your average Six Flags.
Horizons appealed to a sense of wonder and optimism about the future...there was story going on there of some of the best kind...the kind where your imagination is challenged to consider the possibilities. If updated it could have continued to inspire generations to come. Now we'll get yet another ride that will require a lengthy break in a child swap waiting area for many families, and will most likely not kindle that same sense of "possibility".
You know, it takes a whole lot more talent to create a great family ride than to create a ride that has a more limited audience...there was a day when the time and effort were taken. None of the recent family rides has been what I could call "great" (all are enjoyable...but there are no WOW experiences). It seems that creativity has been traded for loud noises, scary stuff, and lots of motion. There are many newer experiences at WDW that, with some creativity, could have really been truly family attractions. Does ITTBAB really have to be so scary and loud to be enjoyable? Actually, I think if it weren't so darned loud it wouldn't be nearly as scary to little ones.
Don't get me wrong...a few thrill rides aren't a bad thing...but when the focus of all the creative elements in ride design is on thrill it will eventually change the feel of the parks entirely.
Of course I'm probably the only person who will dare speak up for the under 5 (or more timid older children) crowd and their parents...most people seem to like to pretend that tiny people don't exist, or deserve barely the same respect as the family pet. (Sorry...that's my child advocacy side popping out!) Hmmm...what was it Walt wanted for his parks? A place where parents and children could have fun together? I don't think that statement was qualified with "over 40" tall"
Oh, what was the subject?

Oh, yeah....Horizons. We miss that one a lot...my kids never got to see it.
