I thought the point of the optimize option was to give you the best options for your selected attractions, right?
I had gone through and made my own plans originally and have been tweaking them here and there (I'm a BIG planner so I'm constantly looking, seeing what I can do better, etc.). I was curious today, so I copied those plans, took out my scheduled FPP, using the same attractions, I optimized and then added FPP in where they should go based on the new plan. The results were interesting to me. I found that about half the time, my evaluated plan was actually better than the optimized plan. Below is a summary of the results. (And for the record, settings were very relaxed walking and minimize walking - I have arthritis and trying to do this without a scooter!) Main times I am comparing below are in line time and walking time.
Day 1: Epcot partial day - Future World - The optimized plan was better on both
Day 2 - Animal Kingdom (did NOT include Pandora) - The optimized plan was better on both
Day 3 - MK (Adventureland/Frontierland/part of Fantasyland) - The optimized plan actually saved almost 30 minutes of in line time; however, it added almost 30 minutes of walking time, even though I had minimize walking selected.
Day 4 - HS - very similar to day 3 - the optimized plan actually saved almost 20 minutes of in line time; however, it added 20 minutes of walking time.
Day 5 - Epcot - Original plan with Test Track and FPP for Frozen - my original plan was 13 minutes of in line time and 8 minutes of walking time shorter than the optimized version.
Day 5 - MK Nighttime (part of Fantasyland - Fireworks) - My original plan saved 14 minutes of in line time and 11 minutes of walking time over the optimized plan.
Day 6 - MK (Tomorrowland, parade, part of Fantasyland) - the optimized version was better - 13 minutes of in line time and 31 minutes of walking time.
So I guess my question - have you found that your plan ever comes out "better" than the optimized plan? And is there a reason to use an optimized plan even when the wait times and walk times are lower in my plan?
