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!
I won't answer the questions for you, but I'll translate what they mean (if you still need help after this, leave a comment (: )
1.) At what hour do they leave the house? (3:00)
2.) What do Inés and Cecilia see? (shoes)
3.) Where did Inés lose the money? (In the sports shop)
4.) Did you return to the store to look for it? (Yes)
(Not sure how well I did on 4, If I remember right "buscarlo" is an example of a reflexive verb.)
