Anyone done this?

First off, we just returned from six nights at WDW...3 at BWI and 3 at the WL. As you all know, both hotels are AWESOME.
Anyway, we had 4 day park hopper passes. Day one was MGM. Day 2 was AK and a little time at Epcot. Day 3 was MK. On our last day there, my wife, my kids (5&4), and I were not sure what to do, so we decided to do it all. We hit all 4 parks. Woke up early and went to MK at opening. Went on Splash twice, BTMR once, Dumbo twice, Peter Pan twice, Small World twice, and Snow White. Entered the park at 9, exited at 11:30.
We then took the monorail to Epcot. Visited the left side of the park. Example...started at Test Track and went around that side to the Liberty Inn For lunch. We then headed back the way we came. Did TT once and Malestrom once. We were out of Epcot by 2:30.
We then bussed to the AK because the kids wanted to see ITTBAB again. We did that and then actually headed back to WL. It was about 5 by the time we got there. We swam, ate dinner, and then drove over to MGM to catch Fantasmic! We got there at 9:05, so we prepared to go to the 10:30 show. Well, they were letting some in for standing room only, so we caught the last half. We then got in line for the second show and enjoyed that one with great seats. When it was over, we returned to the WL at about 11:30. Very long day.
My question is...who has done all 4 parks in the same day, and how did you execute it. I found it to be not that bad, as we hit only the rides that we really liked or may have missed the first time.

I have done all four parks in a day, but with two adults, no children. I'd have to review my trip report to remember exactly how we did it, but I believe we started by taking a bus to MK at opening, hitting Space Mountain, Buzz, Pirates, Splash, and Big Thunder. Then I believe we took the bus to AK, did Safari, Lion King, Tough to be a Bug, and Dinosaur. Then took the bus to MGM, did Millionaire, RnR, and Tot. Then we took the bus to Epcot, did Test Track, drank around the world showcase, and saw Illuminations. I think we fit some other things in there, but that sounds like the basic jist of it. This was on a Monday in September so the crowds were non-existent.

We did four in one day, again just adults, no kids. We started at AK for EE, (Safari, 2 trails, Primeval Whirl, Dinosaur, Lion King) were gone from there by 10:30; then to MK. We did all the mountains, Haunted Mansion, Buzz, Pirates, and lunch. Then we monorailed to Epcot, stopped at TT for single riders line, and over to Japan for Kaki Gori. Then we took boat to MGM. We did RnR and Tot via fastpasses. Then Beauty and the Beast, Star Tours, One Man's Dream, WWTBAM, and dinner at Backlot. We took a boat back to Epcot and enjoyed the countries at leasure. Got a spot for Illuminations. After that we headed to FW and rode TT one more time. Shopped a little in Mousegears and then walked back to BCV. Full but very fun day. Started at 7:00 and ended at 10:30. This was done in January when the crowds were extremely low and it was a little cold.
