We live 1000 miles away and in my personal experience with my daughter, it was totally worth it. She signed up for a Bears Day event in late March of her Junior year. It was the very first stop of a week long college trip road trip all over New England, upstate NY and Pennsylvania.
The Bear's day event was on a Friday. She was able to schedule a meeting with the head coach of her sport the day before, so we got in and went straight to the academy for that meeting.
On Friday, there was a briefing for all the bean sprouts (what they call high school visitors) and parents. Then then a bunch of cadet chaperones came in and picked up the beanie they were assigned to. If I recall, many of the chaperones were 4/c cadets and they tried to match up kids with cadets in their sport. Then the kids went off and spent the day with the cadets. Classes, lunch, any meetings they may have had, etc. It was cool because the 4/c cadet who took my daughter around ended up being a cadre when she was a swab and then teammates. Meanwhile, the parents stayed behind for some additional presentations about admissions, academic programs, and academy life in general. Then a firstie took us on a very thorough tour, we got to check out the simulators, look at some cap stone projects being worked on, etc. I think the day wrapped up around 4pm.
Let me just say, after that day, we pretty much could've punted the rest of the schools on our trip and just went home. She wasn't really interested in anything else after that. But, we drove many more miles, visited 5 more schools, she met with 5 more coaches and we had an incredible time.
More than anything, that Bear's Day visit really planted the seed that she wanted to be an officer in the Coast Guard - even if the Academy didn't pan out. Then when she did AIM 3 months later, it really sealed the deal. All of her college choices were academies and senior military colleges that had a somewhat direct path to commission in the Coast Guard, and also be recruited for her sport.
Every one has different experiences, but for my kid it was a rather pivotal visit and worthwhile for sure!!
