I know that grooms don't generally come to forums asking questions like this, but I'm a groom attempting to keep the sanity (and the happiness) of his bride-to-be, so here I am seeking advice.
As the story goes, my fiance ordered and put together enough party favors for 200 guests, as she and I were fairly certain this was on the high end of the number of people that would attend. The bride's mother, however, invited a large number of people on her own that we weren't planning for (another story all in itself)), effectively sending the number of likely guests above 200.
The party favor in question is a box of jelly beans with a homemade sticker with our names, the date, and a little saying on it. Her plan was to place these at each table setting, meaning we'd need one for each guest.
My thinking, from the perspective of a groom, is adult men won't take them, adult women will take them to be nice, and kids will undoubtedly grab them. If they were placed at the door on a table as guests leave, I believe no one would ever know without counting them that we're an estimated 30-40 guests short of having one for every person.
My bride-to-be is stressed to the hilt because a task she had completed is now something she will have to undertake again in a very short period of time before our wedding so she can have one favor per person, and I'm curious to hear opinions on whether, in this situation, you would take on the task of ordering and making more, or just rolling with it as-is?
