I would politley thank them for their "loving interest in me and my family", and say that I appreciate the offer, and will let them know If I wish to take them up on it.
Then I would casualy change the subject and ask "how are you? hows your family" etc...
NEVER again will I EVER subject myself to meeting with two or three elders in a biased setting where I have no idea of their intentions of agenda!
I have seen how skillfully twisted they can be at manipulating situations before one even knows what hit them!
Elders have the knack of doing this sort of thing:
"brother do you think the sky is red?"
"um no, it is blue...."
"but if jehovahs advises us through his organisation that it is red, would you agree?"
"um well, yes, I mean, no...I mean...I dont know..."
"so do you appreciate the leadings of the organisation?"
"um sorry, what? I thought you were asking if the sky was red?"
"so do you admit to going against the leadings of gods spirit as evidenced through the organisation?"
"huh!?...whats happening??...the sky is blue"
"so it is obvious here brother that you are being subversive"...
