DB and SIL moved to one years ago; it is lovely and they have a very nice garden (SIL loves gardening). When DB died she had support from friends and neighbours, but the only thing is that, with it being an over-50s site people do die more frequently (sorry, but you know what I mean) and she has lost a lot of her neighbours too.
I don't think you are allowed dogs, or, is so, only small ones. There must be cats but I've never seen one there. And you have to pay ground rent on top of council tax. There are restrictions re what you can do which would annoy us - no garden shed (a greenhouse is allowed), not supposed to grow vegetables
but she does.
Everyone seems to take a pride in their homes and gardens and everywhere looks spruce and well-cared for.
