If I wanted to meet the whole family, and you did not want to bring the family, or wanted a second meeting with just you, I would probably just tell you to go ahead and find another breeder. You will probably be a lot of hassle anyway.
I am sorry, but, yes, breeders are busy too. The reason they want to meet the whole family is they are trying to get an understanding of how you manage the kids, and whether the spouse really wants a dog, etc. They are trying to make the best decision for the puppies that they are raising. It takes them longer and is a pain in the neck to have kids running around annoying the dogs. But they do it because they want to make sure the dog is getting a good home. But they shouldn't be expected to meet multiple times with you.
The whole point of a phone interview is to get an impression as to whether or not this person is someone you want to do business with. If that isn't good enough, meeting in person without the family isn't going to do it either. And you are just being a pain. Generally, from a breeder's perspective, these people don't make good customers. They are people who are looking for any reason to knock people off their list.
And that is fine, if you want to wait until you are too old to manage a shepherd to find someone who meets all your expectations.
