Thanks ladies, for providing me with honest insight as well as suggestions. Since the other bridesmaid is going to be bailing on me and I will be the only one actually throwing the shower, what I say goes, and that means no games.
I'm thinking of going by Bed Bath and Beyond and picking up one of those containers of frozen cosmopolitan mix. Mmmmm... I know how to make some cute hors d'oeuvres too, so I should be safe.
The only funny thing I did at the last bridal shower I threw was we wrote down anything the bride said as she opened her gifts that could be taken the wrong way. Then, we read it out loud as a list of things she'd say on her wedding night. There were some good ones! I will probably ask a guest to do this so I can write down who got her what.
The other thing I'm doing to keep the guests entertained is I'll buy a little book where guests can write their wishes to the couple and present it to them as a present at the wedding.
