The MG Elite handbook excerpts posted can not be interpreted or judged as presented. Each one of those is a cropped, individual screen capture of a specific part. You need the complete handbook to get the context and any extenuating circumstances or additional/alternate guidelines. It's entirely possible that each of these are bullet points or paragraphs where other circumstances/rules are handled in surrounding paragraphs/bullet points.
FWIW, I have gladly signed documents with most of these items included. Here's the truth about the versions *I* signed (which could easily have been given this kind of selective-screenshot treatment):
1) In our handbooks, the portion about parent viewing also contained a paragraph that said that parents may watch a full practice a certain number of days a week or month, but that parents watching every day is detrimental to the progress of the athlete. Apart from those full-practice-viewings, 15 minutes were allowed daily at the beginning and/or end of class. One gym asked that you tell the coaches when you intended to watch a full practice, but others did not. Most days, someone was watching because of the team size, but there were always multiple adults in the gym any time a minor was present.
2) The revolving door policy wasn't explicitly stated but was understood. It disrupts the team for people to come and go at will. They want you to be committed to the program and trust them. From what I've seen/read, many gyms dislike "gym hopping." It's not good for *anyone* for gymnasts to be constantly changing gyms. If there's something that you feel is a real problem with a gym, leave. Why would you go back? If it's not that important to you, why leave? Would your employer like you leaving at will and returning when you feel like it? Would you want an employee to do this to you? No, a gym isn’t your employer/employee, but team isn’t a rec class. Continuity is important.
3) The vacation policy was a recommendation. Sure, you can take another vacation (the number of days may be limited; more on that later), but the suggested vacation week is one when the gym will be off. Your kid will not be trained, so it's a good time to take a family vacation with minimal impact to training. None of my girl's gyms forbade other vacations, but the coaches wanted to know the days so that they could plan. I was told that it's better if they train all the girls at the same time on things at certain stages, and if there's going to be a kid missing for a week or two, they'll rearrange their plan so that everyone is present for it. After a "gym-wide vacation", they are all on the same page and can all come back up to speed together. For the more competitive gyms, no they don’t want excessive vacation time because it affects the child’s gymnastics and fitness. The vacation guidelines are made with the assumption that you and your child also want for them to be competitive and successful.
4) Elite gymnast vacations. My kid isn't Elite, so I can't speak to this directly, but I was told by a coach and a gym owner/manager that when a kid is Elite, continuity is crucial. Taking more than a day or two off can slow them down considerably. I can't recall the stats I was told, but I think they said that for every extra day off, it will take (I think it was) about week to get back to where they were. If you and your kid are going to go through everything it takes to get to that level and are lucky enough to have all those stars align.. good gym, good coaching, talent, health, 'right age', mental toughness, flexibility, etc.. ALL of that.. If a vacation makes that big of an impact to their fitness, progress, and safety, wouldn't it be better to make informed choices about when to take vacations and their suggested duration?
5) Some are condemning the medical release portion, but there's not enough information provided to indicate if the parent is *not* informed before the gym makes medical decisions (aka, this is just the release. Perhaps the prior paragraph says that the gym will try to reach the emergency contacts but if they can not, they will need permission to act in the best interests of the gymnast.) As such, they'd need this document on file. You want them to be able to take your child to a hospital in the case of a serious emergency where you can't be reached or can't arrive in time. If it comes down to a serious emergency, which hospital they go to won't matter as long as your child can get treatment quickly.
