and then turn her room into a den and enjoy!

LOL, yes.

Keep in mind there's a continuum of visit-engths that will sort of take care of itself: at first you'll want her to stay for long visits-- all summer, and more-- and she may indulge you. Then a point will come when you both know that 2 weeks is TOO LONG. Then you'll visit back and forth a week or less at a time, maybe for several years. Then the longer visits will work again, if not too often.

Then you'll fit into HER home when you're too old to be alone. See?
