Will someone please check my work?

Question

Hello I put what I am saying in English first and then I put what I am trying to say in Spanish next. Will you please check and correct my mistakes/ misunderstandings. Thank you in advance. Monica

I want my best friend to go back to school and not be lazy.
Quiero que mi mejor amigo para volver a la escuela y no ser perezoso.

My professors always ask me to write neater.
Mis profesores piden siempre que escriba más aseado.

My doctor prohibits me to smoke.
Mi médico me prohíbe fumar.

I leave Seattle for Mexico on December 27. Next I arrive in Mexico City and a limo picks me up at the airport. The limo takes me to my hotel where there are fresh flowers in the room. Over the next few days I will visit the countryside of Mexico and set aside a few days for relaxation. I will depart from Mexico City on January 4 and arrive in Seattle.
Dejo Seattle para Mexico el 27 de diciembre. Siguiente llegue a la Ciudad de Mexico y una limusina me coge en el aeropuerto. La limusina me lleva a mi hotel donde hay flores frescas en la habitación. En los próximos días visitará el campo de Mexico y dejar de lado unos días para relajarse. I partirá de la Ciudad de Mexico el 4 de enero y llegará a Seattle.

Answer 1

Monica, in case you have any doubt, take Lazarus' word over mine here. I actually didn't mean to leave "Partiré," and only was correcting your conjugation error in "Partirá." We don't usually use partir for people.

Answer 2

"Dejar de lado" and "apartar" sound a bit strange. I'd say "voy a visitar... y reservar/guardar unos días..."

I'd say "Salgo de México para...".
You can also say "...escriba más claro", as "claro" can also be an adverb (this option is more common than "claramente").

Answer 3

Thanks James.

I made quite a few minor corrections, so check carefully. Looks like you did a pretty good job, though.
