Well, I have been checking 4-6 times a day, maybe slightly disadvantaged by being 3 hours behind the East Coast. I have been doing this for about 3 weeks.
I started with nothing, and I mean NOTHING. I have gotten a 520 CRT (after picking up and then cancelling a 10 AM and an 810 PM), a 635 'Ohana (for dinner), an 805 breakfast at Crystal Palace and an 8 AM at CM.
I think you will get what you want if you are flexible--like for the CRT, I was OK with breakfast on our MK days or dinner any night--because we will be going back to the hotel to sleep and swim anyway, so it didn't matter which park we returned to later. Not that I wouldn't prefer it on our MK day, in case DD decided to stay awake, but given that people start planning 6 months out, and I had 6 weeks, I think it's worked out pretty well.
Best of luck. The people on this board are freaking amazing and so very, very helpful!
