The last 2 times we have visited Disney we have gone the first week of December and usually waited until about halfway through the trip before we shopped and had a very hard time getting our ornaments finished before we left for home. They were about a week or 2 out with orders. I would make it a priority to shop at the beginning of the stay to try to alleviate this problem. Also if you purchase ornaments at DD keep your receipt and you can go to christmas store at MK and have them done. They only take orders for what they can get done in a day, so make sure you get there first thing!! We almost had trauma last time, as we would not have had finished ornaments arrive until after Christmas if we would have used the DD store. I made a note last time, but this year we are visiting in November so wait should not be too bad, but we are shopping for ornaments one of our first days we arrive.
