We did this in October of 2015. We decided we wanted to hit all 4 parks, do a minimum of 3 attractions in each park, eat something in each park, and use a boat, monorail, bus, and our own two feet between parks.
We started out at DHS because it has morning extra magic hours. We did Tower of Terror and Star Tours, got breakfast at Starring Rolls, and then did Great Movie Ride when the park opened. We decided to do this because we are a family of three and each of those rides is a favorite of one of us (Daughter - Start Tours, husband - Tower of terror, me - GMR). If we had it to do over again, we'd likely do RnRC first, head to Tower, then Star Tours grabbing breakfast on our way out of the park. From there, we grabbed a boat to Beach Club and then walked to Epcot. This took more time, but we wanted to get in the "walk" (and yes, I'm sure there are people out there who would consider this cheating). We had fast passes here and did Spaceship Earth, Soarin', grabbed a snack at Sunshine Seasons, and then did Gran Fieta Tour. We had a fast pass for Nemo, but decided to burn it because we could do Gran Fiesta Tour and leave before our FP window opened. We then took the bus to Animal Kingdom. Because we were getting there in the afternoon, it was less crowded. We were able to switch our Epcot fast pass to Everest. We also did TriceraTop Spin before our lunch reservation at Yak and Yeti (we had been wanting to try it). We were early for our reservation, but we are Landry's Club members and one of the perks is getting the next available table, so we were seated early. After lunch, we headed to the safari. Unfortunately, it got held up due to animals refusing to move from the path, but we were making such good time that we didn't care. Anyway, with how the FP+ system works now, I'd be getting new fast passes from my phone for Animal Kingdom instead of waiting in line. At the time, you had to go to a kiosk. After Animal Kingdom, we took a bus to Polynesian and then took the monorail to Magic Kingdom. We hopped on the train at Main Street and rode it to Tomorrowland where we did People Mover, Carousel of Progress, the carousel, and Philharmagic before stopping at Gaston's Tavern. Then, we hopped on the train to complete our loop and took the boat back to our resort (Wilderness Lodge). It was great and we even had time (and energy) to play in the pool. I'm not sure how it would have worked had we not hit a park with morning extra magic hours. We got to essentially take advantage of 2 parks rope drops (DHS and Epcot). That really helped. Otherwise, I know we wouldn't have done a table service lunch.
