Don't get me wrong. My experience has not been it is a wild west free for all of everyone moving around. Have I heard of some whacky stuff like an entire team not returning to tryouts the next year? yes.
On one hand, if parents are not happy with how an organization does things, they have the opportunity to explore other opportunities. On the other hand, some orgs get accused of constantly just doing whatever will make the parents happy and parents will use the threat of leaving to get what they want.
Another good thing, is if you do your HW you can find the org that is right for you. Some, are very strict in terms of practice attendance, lateness, practice uniform. for example, miss a practice and you sit a period or a 1/2 period. Others are a bit more expensive, but you get more. For example, uniforms are included in tuition, more practice time, more games, more tournaments included, paid coaches. They will also have "full" teams in terms of roster size and the better teams will shorten benches in close games.
On the other end, I know of 2 that are the opposite. One, tuition is less than 1/2 the tuition at mine. However, teams get their 2 practices per week, 6 pre-season games, 16-20 league games and that is it. Volunteer coaches (nothing wrong with that). Might be able to pick up a few non-league games if you can find a suitable opponent looking for a game that has ice. Hard to do though if you can't reciprocate and they dont really get additional ice slots to fill in with non-league games. They can go to tournaments, but the parents either have to pay or they have to fundraise. They keep rosters small about 10-13 skaters, so kids get plenty of ice time each game. Another prides itself on being a "family focused" program. Their goal is to get kids as mites and have them stay together until they graduate HS. They will get a few new kids here and there, but it is usually a friend of a kid on the team, a family who just moved to the area. They don't actively recruit with the intent of increasing the W's against the L's. Basically, if you were on the team as a 12-year old, so long as there were no issues, you will make the team when you are 13. They are not worrying about hanging banners. Their tuition is in line with the rest of the league, but they will get additional ice slots for non-league games, they will have 1-2 tournaments entry fees included in their tuition. I know someone whose kid is older than mine and played there. Said it does cause some kids to leave because they want to be in a more competitive serious environment, but I think that is fine. Can't please everyone and if they do what works for them, then so be it.
I know of another (not one I would ever consider just due to the location) but the players have a very strict dress code for games (ridiculous if you ask me, but whatever). Secondly, the PARENTS are expected to buy the team sweatshirts and hats and wear it to games. They are expected to go out for breakfast/lunch/dinner depending on game times after almost every game. Aside from the location, that is not for me. I am ok with the occasional (1-2x per season) team lunch or dinner after a game, but not almost every game. But again, to each their own.
Point of this yapping here is that I like the idea that families can find the program that works best for them if their closest program is not the best fit.
