Oops just noticed now I made an error where "el fiesta" is written twice :/
I'll send this to our Spanish expert, SraJMcGin.
When you study Spanish, the first thing to keep in mind is: 1) gender (masculine or feminine) and 2) number (singular or plural.)

When addressing someone, a comma is required after Hola, Amigo

When studying verbs, be sure the subject and the conjugated verb match: Tú eres

gender = un día de fiesta de San Valentín.

Days of the week and months of the year are not capitalized plus check spelling in a good dictionary: febrero.

La fiesta empieza (a stem-changing verb e--->ie and it's an -ar verb)

con un desayuno (spelling) y termina con una cena.

Here is a place for a familiar tú com mand = Lleva

a + el = al BUT this word is feminine = a la fiesta.

Probably you will have more than one mariachi? = mariachis.

Drop "Muy" = Yo prefiero.....un pastel (gender)

Con amor (one possibility but not the infinitive amar = to love)

May I suggest that you rewrite the entire paragraph, to be sure you have corrected all the errors. I'll flag this and come back later to check.
