I think I'm understanding what the OP is saying (correct me if i'm wrong)- She is going there to learn, and is happy to learn and get experience with their way of handling/care/etc when it regards their own horses, but the stuff that doesn't work for her own horse, she doesn't want to be forced to use because it's the norm where she's going.
Many people talk about learning from trainers and say 'take what you can use and leave the rest', it doesn't mean you ignore what the trainer is saying, you still learn of the techniques and the reasons behind it. Even if you don't use what they've taught with your own horse, you still have the knowledge of what was said and can use it should you find another horse that responds better to that technique than your own.
