My family and I are planning to go with a handwritten pre-planned tour of the parks, no LL's, no smartphones, just some paper notes and a couple of meal reservations. If we catch a long line or two, we will just go to something less crowded. Not sure how it will pan out, but I hate the idea of spending even more cash on LL's and even worse being stuck with my nose in a phone screen all day. We want to enjoy WDW the same way we did 10 years ago and will spend extra time in our resort, take it easy and give it a whirl. Anyone else tried this?
I haven't tried this, but a couple of things:
1. I take my phone and I'm not looking at it all the time. I'm looking at it for wait times, to take photos, to mobile order, and to see when the next parade/fireworks/show happens. There's zero need to have one's nose buried in it
2. I laughed at your "catch a long line or two." Unless you're there at a very very very not-busy time (maybe mid-August?) you are going to catch more than a long line or two. More like all the most desirable attractions, some with 2- or 3-hour waits.
Your only hope for riding the top-tier attractions is to (a) utilize Early Theme Park Entry--if you're staying on-site, that's 1/2 hour before park opening, which means leaving your resort room about 90 minutes before ETPE in order to be at the front of the line. This strategy will help you ride perhaps one or, if you're very lucky, two top-tier attractions at each park.
And (b) stay until park close and get in line for the biggest draw at each park shortly before closing time or during the fireworks show at MK or Fantasmic at DHS.
You haven't been in 10 years, so you haven't been to Pandora at Animal Kingdom and experienced Avatar Flight of Passage, arguably the best ride in all 4 parks. The line for this can be 3 or 4 hours long.
You also haven't seen Star Wars Galaxy's Edge at DHS. Star Wars Rise of the Resistance is an amazing attraction with innovations not seen before at WDW. The only way to ride this without a long line is at park opening, when it's sometimes not open yet, or at park close. Sure, you could do single-rider line, but that line skips two of the most fun parts of the attraction. I advise against it.
At Epcot, without ETPE you are going to stand in line forever for Frozen Ever After and/or Remy, two rides that are super popular and both have the most boring queues at WDW.
Surprisingly, even lower-tier attractions like the People Mover can have very long lines these days, depending on when you're there, what time of day, etc., etc., etc.
These are just a few examples. I hope you are researching what it's like these days at the WDW parks and planning accordingly. With a plan you can do this even without LLs. But without a smartphone? That seems like a way to ruin your park time.
