Answer: Every proper sentence in Spanish must have a subject and a verb. There is also a proper place for subjects and verbs in a sentence. Begin a sentence with the subject (the person, place, or thing you're talking about). Follow that with the verb, and then the rest of the sentence (where, how, etc).
The sentence is incorrect because of the words dorms and Queen .
The correct sentence is Es importante que duermas un poco antes de la excursión.
Hope this helps and have a wonderful day!
