We Have gone every January for the past 6 years. My kids are now 9, 7, 4 and 2. My advice is to make sure that you take a break every day in the middle of the day to relax, nap, swim, etc. We use to wait until the kids acted tired and then we headed back to the room but we soon learned that was a mistake. By the time we got back, there was usually a meltdown. If the kids do nap, leave the park an hour before their usual nap time. This will allow a relaxed trip back and will allow you to feed them lunch before they nap. Other thoughts - Since the OKW pool is pretty laid back, pool hopping one day may be fun. For my kids, meeting the characters was and is a big hit. We found the best place to meet them was at the character bus right in front of the World Showcase shortly before the WS opens. We always take about every third or fourth day off from the parks to do something different (mini-golf, swim, shop, etc)..... People sometimes eem hesitant about bringing little kids. IMHO, little kids are the very best people to bring since the Magic in them is very strong and their presence allows you to experience the Magic through their eyes. Have Fun....Rich
