1 year old's weekends are the lobby, the terrace and errands with me. Is that enough?

weekdays are sorted, she's with her caregiver and i'm at school. weekends it's just us. we go down to the lobby, up to the terrace, to the vegetable market, she naps, repeat. we tried one paid class and she spent it eating the mat. colleagues talk about music classes and baby gym for kids this age and i come back on monday feeling like we did nothing. is plain unstructured time at 1 fine, or should i be finding her something around tolichowki with other small ones?
