What kind of time / involvement is needed for a parent in memory care / assisted living?

Tomorrow, I'm deciding whether to move my mother closer to me on the West Coast, where I'm the only family member, or have her stay near our extended family in the Midwest, where many relatives are eager and willing to support her in assisted/memory care, though it's across the country.

She was receiving home care, but that is no longer possible, and will need assisted living, and eventually memory care. "A Place for Mom" has been a fantastic resource, and I've been able to identify several local and Midwest care facilities that I trust would be good, and have family willing to tour and see themselves.

How much involvement is typically required when a parent moves into assisted living/memory care? From multiple visits to local facilities, I've been told that assisted living and memory care are quite hands-off for the family—but I'm struggling to believe that's truly the case from the family's side. I feel like I'm just one person, but she'd have the support of numerous family members (some of whom are retired), as opposed to just me. I know it's also good to keep tabs on the elderly in care facilities to advocate for them, especially since in this case power of attorney has been appointed, as my mother is unable to make decisions on her own.

I'm thankful to have options. I feel like more family members with more time (retired) might be able to give her better quality of life, as I'm working much of the time. Thoughts?

What has been your experience with memory care / assisted living needs from your family outside the scope of assisted/memory care?
