Something funny is that my family visited the park on its year of opening in summer 2001 and we had no idea this ride even existed. We even did (what we thought were) all the attractions in the park (and we were gone by 2 or 3pm).
It was that hidden. Just goes to show you how poorly placed the ride is. I didn't know it existed until reading about it years later. I wonder how many other people simply did not know the ride existed.
Even now with Monster's Inc, unless you stumble into that back area of the left side of Hollywood Land, you won't know the ride is there. From the main walkway they could have a sign saying "Monsters Inc This Way" or something, yet they just let that ride sit in a random corner.
This had me cracking up way too much. Amazing.
