I'm never popular when I say this, but, I calls them as I sees them. There is no comparison between 20K and Mr. Toad. Mr. Toad was a straight off the shelf carnival fun house ride. Sure it had a different theme, but, the feel was the same as any roadside show ever seen. I know a lot of people have fond memories and I suspect that they were quite young when they saw it and it just left a memory of perfection in place because they had no concept of "cheap" at the time. I hated it and even though the first time I saw it, I had no real knowledge of Disney Theme Parks, but, from the first moment I took my girls on the ride all I could think was... how did this ever pass muster and get a place in the park.
Oh, and by the way, rumor has it that in Disneyland the subs will be sailing off into the sunset with the new Star Wars addition to the park. Go soon!
