What would I do?? I would not have a bowling party b/c I don;t have the money..
Now that op is in this spot, I would just call the mom and start out with "I can't pick up b/c I don;t have room" and see what she says. And if she says that is ok then she can't come, not a prob. but if she says that she can take her I would just tell her the truth and how much it would cost if she went and see what mom says. mom will most likely say no b/c of the money. I don;t think this is a big deal nor should it be made into a big a deal. as far as calling the mom before hand, how do we know she has her #??? I do know that when my kids were younger and having their parties I did NOT have the #s to any of their friends at school.
