We like the "welcome home" also. I don't feel it's necessary every time we pass through the front gate (as BWVDee said, it could get quite comical), but once at check-in would be nice. I don't see how it's so difficult to say for the CM's ?
As for feeling funny at other DVC resorts other than my "home" resort ------I don't. I feel every DVC resort is my "home".
