I have often wondered this myself. I would genuinely love to follow along with the folks who say they never wait more than 15-20minutes for anything. Do they have a step-by-step touring plan? (I don't want to do that, so I check that off my list as a possibility) do they have a fuzzy recollection of the waits they've actually encountered? (maybe 15 min is an exaggeration that I will never be able to match) do they only go for the first 3 hours, then have a 4 hour resort break, then ride non-headliners on return? (I've never followed this pattern, maybe it's the ticket to no-line success?) I already know I've seen many of those people say that they do ride headliners, so it's not just that they spent all day whirling on the teacups
I have never expected to achieve a 20 min max wait on everything at Disney. I have used legacy FP, FP+ and internet tips for minimizing some waits where I can, but I've never managed a whole trip with 100% lines of 20 minutes or fewer, nor I have ever had the expectation that I *could* do that. I think I probably waited over an hour for Space Mountain on my early trips and 45-60 minutes isn't at all unheard of on my other trips for a few rides. 30ish is common for me. If I were wealthier, I'd surely invite one of these experienced DISers on my next trip and ask them to be my personal guide!! (no sarcasm - I really want to see it in action, I can't imagine it)
We are apparently "those people." We went in June, and never waited more than 20 minutes to ride anything. We had fast passes for Peter Pan, Enchanted Tales with Belle, and 7DMT on one MK day (all in the evening) and 7DMT, Space, and Wishes on another MK day. We arrived at rope drop during EMH on one day. That day, we went to Tommorowland and rode Space first, then Buzz, then Astro Orbitors before walking around to the Rapinzel bathrooms for the "2nd rope drop" before the path to Liberty Square at 8:45. We then walked with the CM crowd around to BTMRR and walked on that, then Splash after with a 10 minute wait, then went right back on Splash with a 15 minute wait. We walked into Adventureland and went on Magic Carpets with 10 minutes, then DD wanted to climb through the Swiss Family Robinson Treehouse, so we did. It was still pretty early in the morning so it wasn't ridiculously hot doing that. By this time, it was about 10:30 am. We walked around to the Christmas shop and browsed, then went to the 11:00 am show at HOP. We had an 11:45 lunch reservation at Liberty Tree, then went on Carpets one more time at the request of DD, waited almost 20 minutes that time, but by this time it was after 1:00. We walked out, caught some of the Castle Show, shopped a little along Main Street, and went back to our hotel for pool time and a break. We swam/relaxed for several hours. Headed back to MK at 7:00. Ate QS at Cosmic Ray's, went on the obligitory IASW ride, no wait. Philharmagic, no wait, Tea Cups, waited for 2 cycles of the ride--however long that is---6 minutes? Peter Pan fast passes. Then to our FP site for Celenrate the Magic and Wishes. After, when the masses are fighting their way to leave, we headed back, first through Tomorrowland and Monsters, Inc, Buzz, Space, (that was almost a 25 minute wait...so I guess that one broke our no more than 20 minute rule) Stitch (yuck). Then we headed around to Fmatasyland, did Barnstormer twice, Dumbo, Teacups (fine with me if we never do that again)had our 11:55 pm 7DMT FP, Carousel, Dumbo again. Then as we headed out (park open until 1:00 am) we went on Space again, two times in a row. We waited, but I can't remember how long, as the line was moving the whole time. But we were back walking down Main Street and bought a golf shirt at 12:37, so we couldn't have waited that long at Space between our 7DMT and our shopping trip. So I'll say no more than 15 minutes each.
This is just an example. We didn't over plan. We followed Josh's touring advice in our method. I planned our FP to be in the same lands in the evening, and chose to ride other headliners at rope drop. But when we were there, we REALLY found it to be true that the parks clear out after fireworks, and that posted wait times are GREATLY eggsagerated.
We DO take long afternoon breaks at the resorts everyday. We enjoy the downtime poolside. We don't rush to get back, and enjoy riding the ferry or monorail in the evening on our way back. We would be exhausted, worn-out limp dishrags if we stayed all day from open to close. But the way we do it works for us, and we don't miss any headliners that we care about. Additionally, we figure if we stay in the parks for those hours in the afternoon, that's when all the long lines have built up that we would prefer to not wait in.
Things we DIDN'T do: we did not see Anna and Elsa, Talking Mickey, or Sleeping Beauty, or Tinkerbell. Those things were not priorities for us. We met characters at meals with the exception of Dug and Russell at AK and Daisy, Donald, Minnie, and Goofy at MK a different day. We didn't go on the Jungle Cruise, DD didn't care about it and that was fine. The Riverboat was closed. Pirates was down for refurb. We didn't do HM because I won't, and my husband and daughter could have but just didn't. We did see other things on other days.
So, as I have said previously, we are only available to go during busy times, but have no problem seeing everything we want to see. We don't spend our time waiting in lines, and it isn't because of impatience as much as it is because I feel that our time is better spent doing other things, like swimming and participating in the pool parties at the resort. There are people on the boards that complain all the time about FP ruining everything because they have to wait in long, long lines for things like IASW, and that just has not been our experience AT ALL. Our FP were kind of clumped together, but I didn't obsess over making them. We stayed on property but booked this particular trip only 47 days out, and we were able to get Fast Passes. (Again, did not try for A and E because we didn't care to, so I can't speak to the availability).
