Because there are no spaces for people who do not know how to enter ... They should have that possibility and worse if they are tourists ...

How do they not know how to enter? I don't understand your question, but there are people everywhere who tell you what to do or how to go if they have doubts.

There are signs that indicate the places and at the same time there are people who guide you for any questions you have.

Friend, look for videos on youtube .. there are many with many tips that are SUPER USEFUL, or ask friends who have already come before .. that has always served me

I did not understand your question or opinion, but you could inform yourself better before your visit or approach an authorized Disney and universal advisor.
