I found this map that might help...

I wonder if you guys could take a Divide and Conquer approach. One of you could go with E while the other go with A on the longer hike. David and Kendall weren't up for it when we were there in 2018 and really just stuck with the Old Faithful loop. When Sam and I walked it, we took the one path to Castle Geyser and then cut over with that walkway leading to Grand Geyser, and then walked back to Morning Glory. The two paths converge at Grotto Geyser, which is probably my favorite looking one of the bunch. I also really like the scenery in the area where you cross over the Firehole River just before getting to Morning Glory. If you keep going beyond Morning Glory, you will wind up on that trail section we did in 2005 that took us to the other side of Biscuit Basin. In hindsight, while our elk herd encounter makes for an interesting story to this day, the couple of pools and little geyser after Morning Glory aren't very exciting.
That seems like an awfully subjective driving test...to the point of sounding unfair. Maybe that's a very American mindset, but it seems to lack uniformity...like someone else might go out driving on an easy day and you wind up with crazy stuff. It sounds like you know what you're doing, so it may just be a matter of persistence with getting tested so you can get licensed. I can't imagine how many drivers would be sidelined if testing were like that in the US.
Yeah, we've used the divide and conquer approach at Disney. That's what makes my husband grumpy. He sees the family vacations as that....FAMILY vacations. We should all stick together. He forgets that people like different things, and if everyone is forced to do the things they don't like to do, they are making it miserable for the people who DO want to do them, and then NO ONE has fun. This is, I think, why he dislikes Disney. He had a GREAT time on our honeymoon there, but I think now that we have a special needs child, he resents having to curb what he wants to do. He started off with the "No, I don't need to ride that....we can't all do that together, so let's go find something we can ALL do." but then after doing that time after time, giving up all the favorites so we didn't have to split up, he realized that was no fun. So then he agreed to split up and take turns...so he gets an afternoon to go by himself and do all the thrill rides I can't do, but then when it's his turn to take A so that E and I can go do OUR stuff, he resents "not getting to have fun" because he's stuck doing the things he doesn't like as much. Then he forgets about that whole day he had to himself the day before, or the fact that I was just with A all morning and I didn't get to do my stuff either. He had spent the entire day from right after breakfast until dinner on his own one day and I had the kids with me. After dinner, E and I wanted to ride Soarin', but A wanted to go back to the resort. A doesn't like soarin' and doesn't like waiting. I didn't figure it would kill him to wait for us to do one ride, but my husband said he'd go ahead and take him back to the resort so E and I could do Soarin'. Then he says "You can respond in like kind at a later time." What do you mean, like-kind? You just spent the WHOLE day by yourself and you think I'm going to owe you more time because you sacrificed time to let me ride ONE RIDE?? He just completely forgot that he had spent an entire day doing everything he wanted to do and ONLY what he wanted to do while -I- didn't get to do my favorites. Then he's thinking "I'm so nice to let them go ride that one ride....now they owe me some time to go do my thing tomorrow!"
I think some of the walking paths at Yellowstone will be fine, but we can't spend all day walking to various pools and such, because A will get bored of it and will complain that his legs hurt. We'll have to balance between driving through and walking to particular viewing points, and he'll be fine. I don't think the divide and conquer approach will be doable because there's no place for A to wait while we go do something. And even if there is someplace for him to wait, he'll be bored with the waiting. I'm hoping that he'll be invested enough in the scenery and animals that he'll be engaged and not mind the lack of electronic entertainment. And honestly, it's good for him to have to make some sacrifices himself. I don't want him to think that our vacations (or anything else) revolve around him and we can only do things if HE says so. He needs to learn to go with the flow a little bit more. I know it's harder for him than it is for us, but it's ok to ask him to do hard things, too....we do hard things all the time for his benefit. He HAS to learn to take turns getting to choose things, and to let others have their fun, too. And he did really well with that on our last Disney trip. He's learning, if we give him the opportunity and explain why it's important. My husband just needs to learn that it's ok if not everyone loves every second...we can all have different favorites and things we didn't enjoy as much. That's ok.
The driving test is DEFINITELY meant to keep the number of drivers lower. Driving is not incentivised here. From really expensive gas prices to narrow roads, lack of parking, and difficult and EXPENSIVE driving lessons/exams....it's designed so that not everyone will get a license. A lot of it is luck....it depends on the driving conditions on the day of your test and what situations you encounter. It's not just a matter of knowing the laws and using proper driving procedures. It's how well you evaluate the traffic situation and how well you handle the car, including shifting, checking mirrors, etc. Like, they are watching you to make sure that you are looking in the rearview mirror before you brake, or before you pull up after a light. If you don't check your mirror as you do those things, it counts against you. Most people do not pass the driving test the first time. And the written is designed to be hard, too....most people I know took it 3 times before passing. I passed the written on the first try, but have more problems with the actual driving. You can't really STUDY for that...you can only practice, and you can only do that during lessons, which cost 50 euros per hour. So to get the shifting to the point that it is second nature, it takes a lot of lessons when you are only doing that for an hour a week. Building that muscle memory takes time. If there were a way to practice without paying for a lesson, it would be better, but that's illegal here. There's no such thing as a learners permit so you can practice.
I can see how Wilderness Lodge at WDW was influenced in its design, by this hotel.
