Baby shower

We’re doing a co-ed baby shower with both our families combined so this will be our only shower for our first baby. We have made a list of who we think we should invite but feel like it may be too much. We have 120 in total but we know there would be a handful that probably won’t show up. How big were your guys’ baby showers and do you think 120 people before the ones that won’t be available is too many for a first baby shower with both families combined?
