I went three weeks ago. I don't stay onsite so my planning is minimal. 9 days before I got there (I had tickets already) I went on line and picked my FP+ selections. That requires committing to a certain park on a certain day, but, I didn't find it that difficult. to work out. I also have Park Hoppers so that help with flexibility. I only went for three days.
Because I wanted to see the demise of the BAH, I decided to park at DHS and go in there in the morning. I asked for three FP's... ToT, Toy Story and Star Tours. The computer gave me 4 groups of three options that included all three. There were morning ones grouped together so I took those. Done! I then felt that taking the boat ride from DHS to Epcot would be fun. Never did that before, so I made an ADR for Seven Dragons in China for 5PM. Again they gave me a selection of available times. I rode the FP's that I had and also went to Indiana Jones, The Muppets, GMR and others before I left at about 12:30pm for Epcot. Epcot is always a hassle because of it's size and trying to do everything at once so my thought was to do World Showcase (since the restaurant was located there) in the afternoon. I did all the Pavilions that I wanted to see (i.e. Mexico, China, France, Italy, Japan, Norway, United Kingdom and then made my way to dinner. Took the boat back to DHS, found my car and headed home. Now that may seem like a lot of planning, but, it was no problem, I just decided my must sees and fit the rest in around it. Without being tied to three meals a day ADR's, I was able to be very flexible about everything else.
Day Two: Epcot in the Morning. I really was only interested in getting a FP for Soarin, but, had to choose 3 of them, so I took Soarin, SSE and Mission Space. I travel by myself so I just use the single rider line at TT. Again, with the grouping of choices I was able to find easy FP's for mostly morning into Early afternoon. I did a quick service lunch and at about 3 pm my old body started to give out. Just for fun, I hopped on the Monorail and rode over to MK and back, got my car and headed back to my hotel. I rested the dogs for a bit and had dinner at one of the millions of offsite restaurants (no reservations required) and then went to MK for the evening. I got a bonus with that because as I was sitting on the tram from the parking lot at TTC, I happened to look over to my right and was able to see the Space Rocket launch from Cape Canaveral.
Anyway the only thing that I knew would be a problem was the 7DMT. It is impossible to get a FP for that without a long advanced try. I did ask if one was available when I got there, but, both the CM and myself got a chuckle out of that. Instead I wandered around in the area, rode the People Mover, and saw the Laugh Factory and Carrousel of Progress, relaxed and did a little people watching until the Parade started. I then went to the stand-by line at 7DMT. The time on the entrance said 70 minutes, my app. said 60 minutes, but, I decided that if I wanted to experience it, I would need to bite the bullet and get in line. From the time I walked in the queue until I exited the ride was just less then 30 minutes. Well, worth it... It is a cute, albeit short, ride.
I don't remember what I did after that, but, by the end of the Parade and before the Fireworks I decided that I had achieved my goal and headed on out.
Day Three: All MK! Made handy FP+ times for Peter Pan, Pirates and HM. The last two probably didn't need them, but, I got them anyway and just spent my time going from one to another seeing most all that I had time for that day. I had made an ADR for Liberty Tavern for lunch, did that one and again just did other stuff as it struck me that I wanted to do. Yes, there was some time spent in lines, but, nothing that I thought of as out of reason. I left late in the afternoon, tired and pleased that I did just about everything that I wanted to do. Sadly had to leave for home the next morning... so that ended it.
The moral of the story, if you can line up FP's then indeed do so. You would be amazed at how much easier it is to plan your day once those are in your hand and are not having to run back and forth to (maybe) get one. It doesn't hold the same spontaneity that there was 20 years ago, but, with just a little effort it can be quite relaxing.
