EFTP/STEPUP

Does anyone know anything about the summer bridge programs for engineering students? My son will be a freshman in the fall and both programs seem to offer good opportunities to get acclimated to the engineering school in particular and to college in general. STEPUP looks intense, but EFTP seems a little “light”. I’m also wondering what the campus is like in the summer (we live out of state so he won’t be able to come home on the weekends). Do many students stay at UF for summer sessions? Are there things to do on campus over the weekends (especially for incoming freshmen)? Thanks.
