Translation:Many angry men and women go out from the expensive but bad hotel.
Here, the focus is on the angry men and women. They leave the hotel. The verb is not so much emphasized, it gets split. Also, it gives the sentence a litte bit of a present continuous sense.
Also, if I wanted to form a question for this sentence, I would ask:
"Who is going out of the hotel?". - Again, focus on the subject.
If we change the verb to "kimegy", then suddenly the verb is in focus. The question I would form is:
"What are/do those angry men and women do(ing)?" - Focus on the action, the verb.
You can take this as a general guideline: verb intact - focus on the verb; verb split - focus on something else.
This sounds temporary to me. Megy ki does not sound to me as they are leaving because the hotel is poor and expensive. They would simply "leave" such a place. Not go out from or leave from it.
