Explanation:

In this exercise, you have to fill in the blanks with the appropriate past tense of the verbs between brackets. As the text is a story that took place in the past (´"last saturday"),  the verb tense required is the "pretérito perfecto simple" conjugated properly according to the subject. The clue to know that the story took place in the past is the initial adverb of time "el sábado pasado". Here follows the model, I have included between brackets the English equivalents:

El sábado pasado, mis compañeros de apartamento y yo fuimos (go) a Acapulco. Nos quedamos (stay) en un edificio muy alto y bonito. En la playa, yo leí (read) un libro y Carlos tomó (take) el sol. Mariela y Felisa caminaron (walk) mucho por la ciudad. Una señora les indicó (indicate) el camino para ir a un restaurante muy conocido. Por la noche, todos nosotros cenamos (have dinner) en el restaurante. Después, en la discoteca, Carlos y Mariela bailaron (dance) toda la noche. Y yo vi (see) a unos amigos de Monterrey. ¡Qué casualidad! Hablé (talk to) con ellos un ratito. Y llegamos (arrive) al hotel a las tres de la mañana. ¡Qué tarde!

Further explanation:

1- fuimos: verb "ir" conjugated in the pretérito perfecto simple of the 1st person plural (nosotros), as the subject is "my friends and "I".

2- Nos quedamos: verb "quedarse" conjugated in the pretérito perfecto simple of the 1st person plural (nosotros). The subject is indicated between parenthesis, but it is not necessary to be written explicitly, as it can be retrieved by the verb inflection. This type of verb is called pronominal, so it has to preceded by the particle "nos", which is the form of the particle "se" for the 1st person plural.

3- leí: verb "leer" conjugated in the pretérito perfecto simple of the 1st person singular (yo).

4- tomó: verb "tomar" conjugated in the pretérito perfecto simple of the 3rd person singular, as the subject is Carlos (él). The expression "tomar sol" is the equivalent to "sunbathing".

5- caminaron: verb "caminar" conjugated in the pretérito perfecto simple of the 3rd person plural, as the subjects are Mariela and Felisa (ellas).

6- indicó: verb "indicar" conjugated in the pretérito perfecto simple of the 3rd person singular, as the subject is "una señora" (ella).

7- cenamos: verb "cenar" conjugated in the pretérito perfecto simple of the 1st person plural (nosotros).

8- bailaron: verb "bailar" conjugated in the pretérito perfecto simple of the 3rd person plural, as the subjects are Carlos and Mariela (ellos).

9- ví: verb "ver" conjugated in the pretérito perfecto simple of the 1st person singular (yo).

10- Hablé: verb "hablar" conjugated in the pretérito perfecto simple of the 1st person singular (yo, indicated between parenthesis but not necessary to be written again because it is understood in the verb inflection).

11- llegamos: verb "llegar" conjugated in the pretérito perfecto simple of the 1st person plural (nosotros, indicated between parenthesis but not necessary to be written explicitly because it is understood in the verb inflection).

yeah no you are crazy
