Hi Dallas,
Yes I do have final (in my book) headcount. It took a lot of threats, cussing and other unladylike mannerism, but I did it!! I do have a watchlist of 3 guests that can go either way at the last minutes so I am still including them anyway. I would determine if they are "strong" yeses or no's and if they change their mind, then they are SOL. Folks know I am not a bridezilla but now its personal because no train or plane waits for this show. If some of the 8 are a coupl, do one bag for both of them and the ones that are strong yeses. If anyone else decides to show up give them like a favor or something in a small favor bag. That way you are not azz out if you are spending like $25 and up on your bags. Use the 20% rule!
Go ahead with your plans, as you can see I have less than 2 months now so in my mind, it is what it is for the guests. People should understand if they are iffy, they cannot expect you to bend over backward past a certain point!!!
