I have stayed at a number of RCI time shares and they can be from luxury to dumpy, it is nice to know ahead of time.
Royal Palms' few time share units(4 I think) are well worn and according to a person I met last week a bit dirty. Nice pool and quiet. No activities. There is a bar and resturant close by. If you can get in cheap, I'd say go for it.
Seven seas is just plain rag tag. No way I would stay there.
If you can get into Banyon Bay it is very nice.
