I am wondering how often it is "okay" to ask neighbors for Mystic Maps. I am at the point where I need 32 maps per expansion, which is more than the number of neighbors I have. I would easily like to expand every couple days as I never have room, but I can't accumulate maps that quickly. Is it best to request a map only a couple times a week? Does it matter? I know that all the person has to do is press "accept," but I don't want to make anyone mad by requesting too often.
