I do not believe that they offer overnight tours for appointees. However - this is from the Class of 2023 Appointee Booklet:
"
In April, Appointee Tours may be offered to provide an opportunity for appointees and their families to visit USAFA in order
to gain an understanding of the Academy environment and envision themselves as cadets. These one-day tours are at the
expense of the appointee, but allow for the opportunity to interact with USAFA personnel more specifically on what is
entailed in cadet life and how to prepare for Basic Cadet Training. Appointees will receive information regarding these tours
when they are offered. If Appointee Tours are not an option, or do not coincide with the appointee’s schedule, please consider
attending one of our campus tours. Although campus tours also include admissions application information, there are many
opportunities to ask questions of a cadet or recent graduate, and to see the campus."
The offer of appointment must be accepted by May 1, 2020. Meaning DS will be able to tour USAFA before the deadline to accept or deny the appointment.
