Elilia, I'm glad to read that your sticking with your program. As a club owner - you know full well what the costs of operations are, and what level of training your team need to be successful. Parents don't. The more successful athetes you have - the more the parents will understand. This only takes time to develop this high reputation. Which, IMHO, should be your ultimate goal. To be THE gym athletes want to go too in your area.
We have clubs in our area that cost almost half as much as our gym, and train L3's - L6's 16 hour a week during the season. (which is beyond nutty in my opinion). During summer, they cut this to 12 hours a week. It's a very popular club, and has a somewhat large team. Here's the kicker: The athletes are very rarely on the podium, even when they go out 40% with awards! I always feel sorry for many of them because I know how hard they must be trying. So, Is this "saved money" or wasted time? Only the individual parent can decide that I guess. I think you know how I feel.
As a parent, I expect good programs and well equipt gyms to cost more, AND that the owners and coaches are also entitled to make a decent living in the process.
FWIW, our L4's do two 2.5 hour sessions, with an optional 3rd 3 hour session on Satuday per week. Im proud that we dominate the podium and that we've taken the team trophy for every competition we've been too in both fall and spring seasons - for the last 3 years. In fact, we've heard about other teams not coming to a competition because our gym was going to be there. So how is this possible with such low training hours? Answer: A good (and well compensated) coaching staff!
We have no penalties to missing a session, or even a week of sessions, other then loosing tuition money. We don't have "make ups", and this is fine with me. I am very much family first, school second, gym third. Thankfully, our club owners are in full agreement with this way of thinking.
Lastly, A little research in your area for other competitve sports may prove enlightening. We have three major swim clubs in our area. Each cost $350 a month, and have 3 a week mandatory 3 hour training sessions. Hockey programs, diving, and cheer/spirit squats are also -- not near as 'reasonable' as gym.
