That's a tough one. I love the CP but my family not as much. No way am I going to wait in the standby line with the possibility of not getting in.
If it is possible to get a hopper, I would see OL at 6:30pm (ish) when they open, then hop to EPCOT, stand behind the rope to see CP (I usually have a fine view), and then grab a spot for Holiday Illuminations at 9:30pm. While I love CP and really love OL (and will miss them), my favorite hands down is Holiday Illuminations and 'Let There Be Peace on Earth'. I have never seen anything like that.
