Actually, I rely primarily on memory and allears.net for our planning.
Since Kitsune and I don't have kids (yet), we don't have to worry so much about logistics and are able to just pick up and go.
Monster, if you and your family DO decide to eat at a table-service restaurant within the parks, I'd recommend making reservations in advance. Waiting for a table can often take a ridiculously long time -- time that could otherwise be spent running around and having fun. It can be pricey, but a lot of the food is so good it might be worth it to plan at least one nice dinner out.
Are you staying at a Disney villa, or one off-property?
