My mom is in a retirement community, a very nice one. They have three buildings of Independent Living, two of Assisted Living, one of Memory Care (Alzheimers, etc.), and one for Rehab (a temporary place that covers normal rehab after surgeries, etc., and also permanent "nursing home" type care). Now that she is in Memory Care, the definition of "nice" changes a little bit. It is about as nice as it can be for a place where you are locked in, but honestly, nobody really wants to live in a Memory Care facility. Declining due to dementia is not the way anyone plans, or wants to end their life. I have no experience with the Assisted Living or Rehab buildings other than guided tours to see what they are like - my mom went straight from Independent Living to Memory Care. While in Independent Living they had fantastic food. Excellent chefs. Menus that rivaled the finest restaurants. Beautiful decor. Lots of activities - ranging from in house concerts, games, parties, etc. to international travel. They would go on Christmas shopping trips to Europe. Cruise ships. Trips all over the US. On all trips they are waited on hand and foot. A lot of that came to a screeching halt with coronavirus however. They do nice day and simple overnight excursions from Memory Care as well, but since mom moved there in the middle of coronavirus they have had those on hold.
Such living accommodations don't come cheap. But if you saved yourself a nestegg, in your elderly years is when you are supposed to be spending it.
