My younger sister is getting married this August, and as MOH I offered to host a bridal shower in her honor. But when we started to talk about the guest list, it quickly grew to over 50 people, most of them from the groom's side. I understand that my future brother-in-law comes from a large and close knit family, and that my sister doesn't want anyone to feel left out, but I'm worried about the cost of hosting such a large party. I live in a small townhouse, so with so many people it will have to be at a restaurant or I'll have to rent a space, not to mention the cost of food and alcohol (the groom's family are pretty big drinkers). I really want to throw a nice shower for my sister and I'm willing to spend money on the event, but I'm starting to feel like I'll have to either totally blow my budget, or have a really cheap feeling event. To make matters worse, none of the other bridesmaids can afford to contribute financially. Is it unreasonable to expect (hope?) that someone from the groom's family will offer to host a party for their side? The groom's sister (one of the bridesmaids) is still in high school, and while his mother did offer to help, it was more in a set up way than a financial way. Basically I'm feeling a little taken advantage of, but I don't want to cause stress for my sister or offend anyone. Any advice on how to handle this delicately, or should I just suck it up and try to cut costs where I can?
