On the RSVP envelope do you just list the address or do you list the people's name too.

Our RSVP cards are coming back to the FH and I.

For example on the front of the envelope do i list

123 State Street
New York, New York 11003

or

Kathleen Smith
Nicholas Black
123 State Street
New York, New York 11003

Ours had both of our names...I must say that I can't recall what others' have said though. I don't think it matters in the long run.

We had both of our names, but on the same line.

I've also seen just the bride's name.
