Just sit back and take a breath. You can plan as little or as much as you want, if you read these boards it might sound like you have to have your days planned down to the minutes and it's not necessary. We don't book fast passes or ADRs in advance but we have been going for a long time. We started going before there was such a thing as a fast pass and standing in line was what you did, so most of the time that is what we do since we rarely know what park we want to go to until we get up in the morning. Know that it is impossible to see and do everything there is to at WDW so don't stress thinking you are going to try. Also know that one person's must see and do or eat at is not necessarily what is right for you. There is no wrong way or right way to do it, it's your vacation, do it your way. Go slow and enjoy the place
