My 67 yo niece has traumatic dementia, and needless to say was many years younger than others in her first Memory Care location, which was very disturbing to her. They were also a "medicate for everything" facility, so she was on far too much medication, and they could not or would not accommodate her lifelong need to snack throughout the day (and she is thin as a model.) Her kids found a small (3 resident) family-run Memory Care residence where she is flourishing - healthy food and cookies are available 24/7, she is off most meds, they have a fenced yard where she can walk as much as she wants, since they are with her 24/7 they know every sign of an oncoming "meltdown" and can work to avoid it. My daughters who are nurses (one with 10 yrs MC experience) will be visiting her this week - we'll see what they have to say.

So don't automatically reject a smaller place - as your Dad's dementia advances, it may be just perfect for him.
