We just planned my D’s trip to visit some colleges during her spring break. She has been accepted to 3 of 4 and will be visiting the 4th at the same time because the schools are clustered together (OH and PA). Of them, she visited two over the summer and has not visited the remaining two. We live in the west, so we wanted to be efficient with travel time and cost. We also have done many summer campus visits (campus tour, info session and sometimes an interview). At the school where she is waiting on an admissions decision, applicants are allowed to sit in on classes.
We decided to not do overnight visits because 1) they are too random - a great or odd host can really skew your child’s opinion of the college 2) they are time consuming 3) your child might not sleep too well and it will add to the fatigue of the trip.
We decided to emphasize class visits, because IMO, one of things you are buying at an LAC, is classroom interaction - both the quality of the professors and the students. Sitting in on a class will give you a sense how engaged the students are in their learning, how collaborative and/or constructive they might be, etc.
At this point, your child has already applied so the info sessions are likely to be somewhat superfluous. There also tends to be some overlap in information between the campus tours and the info sessions.
I also now believe that less is more - two a day is possible but tiring. One a day allows time to visit a class or two, tour the campus, eat in the dining hall, do some people watching, and to get to know the surrounding neighborhood a little bit.
I am somewhat skeptical about admitted student events - the college will obviously be putting its best foot forward and will be generating a lot of excitement. An ordinary visit on an ordinary day is probably a more realistic idea of what being a student there would be like.
If you’re concerned about locking in travel arrangements, you could lock in your dates, airfare (maybe on SW to avoid possible change fees), and reserve a rental car and then wait on the specifics until your child has more information in hand. As was mentioned earlier, nothing will be happening on Sundays so flying out on a Sunday and returning the following Saturday would enable you five substantial campus visits M-F (assuming Good Friday is an available visit date). By avoiding overnights, you can use that time to travel to your next destination. Which 5 of the 7 would depend on your and her assessment of fit, likelihood of acceptance, and her interest. One place where you might consider doubling up would be Amherst/Smith/MHC, given their close proximity to one another. Also, should she not get accepted to all of these schools, you could do some last minute shuffling among the ME and MA campuses.
Good luck and have fun!
