My kids also had legacy at both Penn and Georgetown. Georgetown legacy can be significant - but the level of activity of the particular alum is huge - a recommendation from a director, if your father’s relationships rise to that level, could be significant. Georgetown, though, makes clear that the legacy benefit is realized only during regular decision which differs significantly from most schools, including Penn, where legacy matters only in ED. So, if you are ambivalent and want to maximize the legacy benefit, you can ED at Penn and regular decision at G-town. At the end of the day, though, with both, it does come down to fit and the application matching what the school is looking for and the level of competition with others seeking those same spots (school, major, etc.).
