That was our strategy for ths trip. Wed-Sat we did parks the day after their EE (Wed-MGM, Thur-Epcot, Fri-MK, Sat- AK). It was MLK Weekend, so I thought things were rather crowded. I'm used to walking on every ride in January. Our longest wait was probably 10-15min (BTMRR with a FP!!). Other waits were: Buzz - about 7-10 min, Splash - no wait, we FP, Space Mt was suppose to be 30 min, but they opened up a second line and we were on in 5 minutes, Primeveil Whirl was 20 so we passed, Dumbo was 30 (as usual) after 10:00. Most everything else was only 5-10 minutes, which really isn't bad, but I'm spoiled. Of course, we were there at opening and headed for big rides first (Test Track, Buzz, Tomorrowland Speedway, Peter Pan, Safari)
On Sunday we did do EE at MK. But it was raining, so crowds were thin. We walked right on everything.
I think if you cant do EE, this is your best bet. EE days the parks always get pretty crowded by noon.
