We were there 3/19 through 3/25 for our fourth Spring Break trip. The only day that was crowded was at Magic Kingdom on Friday (3/24) and it wasn't horribly packed. Of course, I intentionally planned each day for the park that wasn't the EMH-early park. The only way I've found that EMH-early works well is to hit the park at opening and ride all you can quickly and leave the park around 10:00 am to hop somewhere else. We're not big park hoppers. I will hop if I have to, but really like to stay in the same park all day if I can.
We went to MK on Monday (3/20), Dis-MGM on Tuesday, AK on Thursday, and MK on Friday. We did the Epcot EMH-late hours on Friday night and it was not bad except for the wait on Soarin' (fastpasses were gone for the night). The longest line we stood in all week was for Splash Mountain - standby was posted at 30 minutes but was more like 60 minutes.
I want to say that Expedition Everest is my favorite attraction now. The imaginears did an incredible job on everything with EE! It's a smooth, exciting ride! The Yeti part was not as scary as I had feared. I have a 6 year old dd and was worried about the scare factor. She loved it and rode it 2 times!
The highlight of my trip was seeing the lights on in Space Mountain! We were about 30 people back when it broke down and they flipped on the lights. That was incredible! I took several photos and was surprised they didn't say anything to me. We had ADRs to make, so we got out of line and they honored our FPs later on that night. I love Space Mtn, but EE is my new favorite roller coaster!
