There is no standard for "daily life" in a retirement community. The most important consideration is for your grandparents to decide what kind of daily life they would like to have, then to find a facility that offers that? Do they want to stay indoors and read and watch movies all day, or would they prefer visiting poolside with neighbors? Do they want meal prepared in a communal setting, or do they prefer to cook for themselves and enjoy quiet evenings? There are many, many options for retirement; there is no one prescription that everyone must follow. Your grandparents should research several facilities before making a commitment.
