But to really tell the whole description would require more than just three sentences, I think. Otherwise, there's really no way to get the point across properly.
It is possible to get the point across in 3 sentences. Think of it as a beginning, middle, and end. Introduce the beginning of the ride in the first, the middle of the ride in the second, etc.
For example, in your Magical Journey's submission, the last sentence "And yes, that means the return of the titular song, which was created by no one less than Richard and Robert Sherman." could have explained at what point in the ride will this song appear? The middle sentence had too much detail in which what the ride will begin with, and you could have split that sentence in to telling you the rest of the ride.
It's just the format. It is possible to tell the entire experience in 3 sentences, you just need a little longer sentences and explain your details.
If you would like to talk about this more, feel free to create a conversation with me as I don't want to distract from the thread more.
