Goodness no, dontomasso. They obviously had caterers (plus parking attendants, an orchestra, etc.) to attend to that, since it seemed like the population of a small city was invited. I can't imagine anyone looking after an event that big without help.

Michael and Kay lived on an estate (much like the "mall" in New York), so I've no doubt that they had servants. Even in GF1, I'm sure they had domestic help in a compound that huge. Yet in GF1 (and this is in daily life, not during "events" like Connie's wedding), we see Mama doing her own cooking; and in GF2, we don't see a lot of staff (if any) going in and out of Michael and Kay's house. Kay does her own grocery shopping and drives the children here and there.

Now I don't think she has to worry about laundry and scrubbing the floors, but I also don't see her spending a lot of money for personal luxuries on herself (but then there is JustMe's observation about her clothes ... )
