I feel like I can add a little perspective here...
My son is a 2019 HS grad who has played at two different schools and now in three different collegiate summer leagues.
The summer after his freshman season (Covid year 2020), he played in the SCBL for the full season. He started just a few days after school ended, and played until about a week before going back to school. He was able to live for this summer with his aunt who was about 30 minutes from the home field. It was also close enough that he could come home on a few of the off days.
Last summer, he played a partial season in the VBL (with some much appreciated placement assistance from some great folks here on this forum - he was in the transfer portal so his previous coach didn't help.) He had a few weeks home before moving up there, and maybe a week or two at end of season. Had a great host family, with 2 players sharing a large private space in the basement.
This current summer, he played a full season in the Coastal Plain League. Had 1 day at home after spring school season ended, and 6 days at home after summer season before he reports back to school this weekend. Again, he had a great host family, even though the conditions were cramped with 3 players sharing a very small house with the family. Team provided a gym membership where he spent much of his free time, but there were also afternoons at the lake and a few rounds of golf. (Proud dad - He also took 4 summer classes and made 4 As this summer.)
In each of these three different experiences, he has made new friends and extended his circle of baseball connections. Players and coaches and team officials and host families and members of the communities he will remember forever...
In each season, he has gotten opportunities to pitch in meaningful games and played in front of enthusiastic fans and tried hard to win championships and help grow the community involvement with the teams.
He's had the opportunity to learn different things from diverse groups of teammates and coaches, and see the world from several vastly different perspectives. On MLB Draft night, he traded texts with previous teammates who had gotten the call. He was proud to tell me how he had gotten outs against several of the guys who had been popped early - and I reminded him of one or two who had gotten hits or walks against him :-)
Yeah, there were several times when it was hard, and maybe a few times when he wanted to be somewhere else, but the value of these experiences is so much greater than having a few more weeks of idle time. I mean, he told me last night that he was really tired in the last few weeks, but that the experience of making the championship series and pitching in Bananaland was something he'll never forget.
And, I never got the sense that there was an overall feeling of going-through-the-motions among his teammates. In all the games we were able to see (in person and streaming,) the team chemistry and enthusiasm seemed incredible.
Who knows what the future will bring, but he sure expects to play as many more summer seasons as possible, and he hopes to be able to get into leagues and situations where he can keep learning and keep getting seen by the folks who can help him go farther in the game.
I'd like to publicly thank @hokieone (and all the others here) who helped him get these opportunities. The contacts he made in the VBL when he was in the portal led directly to transferring to his new school.
So, I guess the point of all this is just to say that for some kids, especially mine, that the summer ball experiences can be some of the best and most influential they will ever have. They will learn much that would not be possible otherwise, and it will benefit them in everything they'll do later.
It's a small sample size, but from my perspective, leagues like the VBL and the CPL don't have too much to worry about - they're providing a great service to their players and their communities.
