Help me research Continuing Care Retirement Communities, please?

My mother will, in the near future, need to move to a graduated living facility. I’d love some tips on research for this. I’ve been Googling, and there are so many sites that come up! Can you help me streamline my research? I know about googling for location and facilities, but I’d really love some tips from those of you who have had to go through this. She still has all her marbles but is very resistant to the idea. Thanks. Isn’t being a Boomer just a kick in the pants?
