The first time you go, it can be overwhelming: There is SO much to see, so many choices / decisions to make, it can actually be stressful. One way to reduce your stress is to go with a touring plan. The major sponsor of this site sells them as well as the Unofficial Guide to WDW. A good touring plan will not only relieve stress, it will reduce the amount of time you STAND in line by up to 3+ hours PER DAY! Follow a plan once, and you'll be forever grateful you did. You'll see more, wait less, and be assured that all the best attractions will be hit. Also, as someone else mentioned, research the attractions. There is more to do in Magic Kingdom or Epcot than can be done in one day. If you knew what you want to skip, it'll make your day easier, too.
