It very much depends on the individual and what stage they’re at.
In the early stages - before diagnosis, but when we were already aware that something was badly wrong - my Mum would agree to go away to a place she’d always loved staying. But when it came to leave the house, she pretty much had to be physically manhandled to get her into the car. She used every delaying tactic she could think of, and became very upset. It was leaving home which was the problem. Once she was at the holiday place, which she could still remember from many previous visits, she was happy and settled.
We’re a few years down the road now, and I’m pretty sure Dad would never risk going away with her. Even if she could be persuaded to go, she wanders at night and there’s a risk of her ending up in a dangerous situation somewhere unfamiliar.
