Aside from character meet-n-greets, watching shows (both indoor and outdoor) what else does your family usually do in the Parks at WDW?
Our family does all kinds of stuff besides rides. Sone of us play "Sorcerers" (the free card game at MK, pick up your starter cards at the Fire Station on the town square), and at Epcot, we play "Agent P's World Showcase Adventure" which is so much fun, and at AK you can do the "Wilderness Explorers" activity as well. At all of the Parks there are always "hidden Mickey" hunts to do. We have been known to do photo safaris or photo scavenger hunts (where everyone tries to get a picture of each item on a list, like Mickey bar, Dole Whip, Cast Member badge, 3 different hidden Mickeys, etc) and we have always engaged in pin trading with CMs at all of the Parks as well. We are pressed penny collectors from waaaaaay back, so we carry pennies, and quarters to make sets of pressed pennies on every trip; there are TONS of the machines scattered all over Disney World!
EPCOT is a great place for not doing rides, simply because you have World Showcase to walk around, and look at everything. I don't think that KidCOT is a thing right now, but there are still the little museums in some of the pavilions (Mexico, Norway, Japan and Morocco all have exhibits about their culture tucked away in their pavilions) and it's just one of the most "strollable" Parks to me.
AK probably has the most "stuff" to do right now that isn't ride-related; I believe they are still doing the animation classes out at Rafiki's Planet Watch, and you can see some of the animals (but no touching, bc COVID-19) and of course, ride the train to and from. I think that the bird show is going on right now as well - maybe someone can confirm that? (We haven't been since January of this year).
I think that HS probably currently has the least amount of non-ride "stuff" to do, outside of Galaxy's Edge. For me, that's worth the price of admission alone, but I could just sit in Ronto's all day and people watch there very happily, so don't go by me! LOL
I'm also the kind of person who buy a Parks ticket just to make that turn from town square to Main Street, and look at the Castle... Just that moment alone is something I look forward to every trip. I love the architectural details in all of the buildings, and how the CMs costumes fit with that. I can't get enough Dole Whip ever, and left to my own devices (and hopefully, the return of the Park Hopper) I would eat at Katsura Grill at EPCOT every.Disney.day. Disney Springs has become one of my favorite places as well; we have a favorite spot (overlooking the springs, of course!) where we sit and enjoy a snack on every trip, and marvel at the Imagineering.
Outside the Parks, we love to ride all of the different boat routes between Resorts and Parks (and at Disney Springs), and during the fall and winter holidays, we will sometimes rent a golf cart and go tour the decorated campsites at Fort Wilderness. (Some of the them are *amazing*!) We also visit the stables at Fort Wilderness to see the horses, and the shops there are some of our favorites in all of WDW!
Disney Springs has tons of opportunities for fun - pin trading, hidden Mickey and/or photo scavenger hunts are all possible there too, and without Parks admission; the same can be said for every Resort hotel at WDW.
It's kind of spendy to consider Parks admission if you feel like you won't have much to do, given the current closures due to the pandemic. Would your kids be OK with a Disney trip where you visited Disney Springs and other Resort Hotels, but maybe didn't go to the Parks every day?
Or, maybe this is the year to consider exploring a theme park closer to home - is there a Six Flags, or something like Dollywood or Silver Dollar City near you? Maybe instead of a Disney vacation, you rent a cabin at the lake, and just enjoy nature walks and cookouts? I'm not nearly as much of a "ride person" as I used to be - my physical issues increasingly make getting in and out of some rides more difficult and painful - but I still enjoy just *being* at WDW enough that I would always plan at least one day in each Park, if not more.
I know it's not a lot, but I hope those suggestions help spark some other ideas for you!
