Honestly, it will probably be pretty crowded. We AP holders are a big force at DL and I went in January, the first day after that short blackout, and it was a pretty crazy day. With CarsLand opening during the blackout, it may be beyond. It should be better in DL over CA and may actually not be too crazy at DL--definitely plan DL over CA on the 20th and probably 21st too. The good news is the AP holders always like to cruise in later and don't have access to Magic Morning Hours. If you plan for the busier rides (new Matterhorn, Peter Pan, Alice, the Mountains or any meet n greets) early in the day or get FPs, you could get a lot done pretty easily. Good luck. I think you'll be fine with a little planning.
