I will be driving from the Disneyland area and want to be at American Girl when it opens. My dilemma is that I can go on a Sunday assuming the traffic will be lighter, but worried the store will be busier. Or I can go on a Wednesday assuming the traffic will be worse, but the store less busy. I have never been here. My girls want to get their dolls' hair restyled and also have lunch. Any recommendations or things I should consider? Thanks!
