We just came back from our trip yesterday. We were there December 16 - December 21. It was crowded, but certainly not as crowded as Christmas week (we were there December 25 - December 30 last year). We used FP+ effectively and were even able to snag some pretty good FP+ after our first 3 were up (got a Soarin' FP+ one evening). Standby lines were very long (up to 2 hours for some of the major rides), so just make sure you schedule your FP+ at 60 days if staying onsite. We will most likely do this week again next year. We had a great time.
