I am a bridesmaid in a friend's wedding and offered to host a couples shower for her. We selected the date together, and the invitations went out a month in advance. I have had one couple RSVP. I was only given mailing addresses for all the guest, and have been told there is a retirement party taking place that over half the guest list will be attending. I said RSVP by 25th, the shower is on the 1st. At this point if the party were to take place it would just be 6 people, 2 of which are the host couple, and 2 who are the guests of honor. At what point do I call it? Can I cancel the shower? Should I tell the bride I will just spend the money for the shower on a really nice wedding gift? Should I just call the couple that RSVP'd? Help!!!
