I am wondering about inviting some extra people to my wedding that is happening in 3 weeks.
Background: I am a graduate student in a small program in a state that is away from my and FIs family. After much deliberation, we have decided to get married here rather than in one of the states our families live in. When first planning the wedding I made the decision to only invite the students from my own cohort (10 people) and not the other cohort.This was because at the time, the other cohort had just begun the program and I didn't know them very well and I wasn't sure if we would have the budget to include them. In total we invited 120 guests and were planning on about 75 to attend since most were out of state. After receiving most of our RSVPs, we are looking at 50 guests (including immediate family and wedding party).
My issue is that our caterer has a minimum charge that was set up when we were planning on more guests and we have also purchased a lot of other things (favors, alcohol) based on more people attending. I really hate wasting money and want to make the most of our wedding budget. I am wondering if I should informally invite the students from the other cohort in my program (who I would genuinely like to have at the wedding) or just bite the bullet on the loss?
