Answer:
Estoy seguro que ellas lo habrán pasado muy bien. Creo que se habrán quedado en el club deportivo que les recomendaron. Allí, organizan actividades culturales y seguro que ellas también se habrán entretenido visitando museos y yendo al teatro. ¡Qué envidia! ¡Y yo aquí trabajando las veinticuatro horas del día! ¿Habrá visto Elena a sus parientes? No sé si ella habrá tenido tiempo para visitarlos. Al final, ellas habrán decidido quedarse en la costa. Ellas habrán ido a espectáculos todas las noches y se habrán relajado leyendo en la playa.
Explanation:
I'm sure they had a great time. I think they will have been received at the sports club that I would recommend. There, they organize cultural and safe activities that they will also have entertained by visiting museums and going to the theater. What envy! And here I work twenty-four hours a day! Have you seen Elena to her relatives? I don't know if she will have time to visit them. In the end, they will have decided to stay on the coast. They will have gone to shows every night and have relaxed reading on the beach.
