Weddingbee boards

I thought I had my response card down but now not so sure. Started thinking that most families we are inviting have 3-5 people in them. This is what I was going to do:

Please respond by August xx, 2010                 

We have reserved ___ seat(s) in your honor

M_______________________________________

___Accept(s) with pleasure

___Decline(s) with regrets

Please initial entrée choice for each guest:

_____Meat                                                                                                                                                                               

_____Fish

_____Vegetarian

But now think it wont get me accurate responses. What does the "M" stand for anyway? I'm guessing that's where guests write in their names? My problem is that let's say I'm inviting my aunt plus her 3 children and husband. How will I know if all 5 of them are coming. I'm hoping they would all initial next to their entree choice but should I also add a line before the accept/decline part to read: "Please indicate how many guests will be attending"

I don't know if I like how that sounds b/c it's becoming too wordy and what if people take it upon themselves to add to the number allowed. what if I scratch the accepts/declines part  altogether and add:

"_____of__5___ guests will attend" for example

Thanks suggestions are most appreciated! p.s. my entree choices will be changed when we know which specific dishes we will be choosing after the tasting, but there will be 3 options.

Thanks!!

Thankd for the suggestions everyone!

Vonnegurl- So did you have to customize each response card depending on how many guests were invited? I was thinking about this but if I get them printed somewhere instead of doing them myself then I guess I could just instruct them on the specifics.
