Living in Santa Rosa we have to (for the time being) choose between Windsor Walmart and Rohnert Park Walmart. Choose Windsor if you possibly can. While Rohnert Park's Windsor may be bigger they actually seem to have less of everything you need - I don't know how it is possible, but it is. I can never find what I want and it is always crowded, with very unfriendly and unprofessional service. The lines are extremely long - you can easily end up waiting half an hour in line. Why? Poor management and poorly trained, lazy cashiers. Windsor's Walmart might be smaller, but it is much much better.
