Cheyenne is a slightly easier nicer walk. If you are off peak try at get one day of the weekend in as sometimes theres the odd show that doesn't show midweek, (although thats less true these days). On peak go mid week. As a general rule EMH and mornings for rides afternoon for shows and parades. Although youll probably know this as you're already veterans! I suspect the next paragraph you'll already know.
Get out during magic hours most days to avoid the queues, Although you'll probably need at least one lie in especially if you do make it late enough for dreams. Ideally you want several days (ideal imo is 4nights 5 days). First EMH in fantasyland, hit dumbos then Peter pan then the rest fantasyland. Next time buzz light years intergalactic spin, the cars one, obitron, star tours (Not space mountain). Next EMH studios park for Ratatouille and Frozen then rest of the studios park. This will probably be the day you'll do dreams if you do it. If you have another EMH hit Thunder mountain otherwise fast pass this on an afternoon youve done the main park.
2 wishes and a prayer was something we did a lot of when the kids were little. At breakfast often with a park map everyone, including adults, would say one thing that would make the best day, one thing that would make an excellent day and one thing that would make a good day. This Might be limited to fit in with overall plan eg to fantasyland, studios park, main park etc. This helped some children understand balance their own needs with others, and helped them deal with disappointment if something was unexpectedly closed or the plan changed. "oh well we didn't get to do..... But we still got you excellent day choice". In fact we did this a lot generally and still do but with more grown up language. It also gave a framework for discussions at the end of the day when we would review/chat over dinner what we have done.
I kinda disagree with saying you can't get a souvenir until the last day. Whilst many things you can get in multiple locations, sometimes you spot something unique or something a child wants to wear during the holiday. When they were younger that budget was for example £10 each day or save it for the final day. But there was some flexibility if for example they wanted a hoodie they could wear during the holiday. Don't buy fragile souvenirs on the last day as the send to the hotel shopping service wont get it back to the hotel in time and you will probably break the glasses in the bottom of the pushchair on the Eurostar 
Watch Disney films beforehand especially Ratatouille, lilo and stitch and Peter Pan. Don't miss stitch live.
Yy to cafe mickey and buffalo bills wild west. If you do both, you may find its more cost effective to upgrade to sequioa.
Really can't emphasis enough windproof!!! Especially in November. If they are mainly buggy bound all in ones may be better to stop that little gap around their back as they are in and out of rides. (At that age I would have one more comfortable in an all-in-one and one in fleece trousers).
Refillable water bottles and squishy mini juice. Even if its cold and they turn off some of the fountains; theres one as you exit star tours half way up the exit corridor (before you hand back the glasses you may have to look left) and one in hakuna matata. All the sit down and buffet restaurants will bring you a jug of tap water for free if you ask.
We found the sit downs and buffets much nicer and worth the extra cost compared eating at the fast food joints in and out of the park. Just being able to sit down and decompress and not having to divide and battle a queue for seats. The kids preferred the buffets as no waiting for food and they could eat all the desserts, I preferred sit down as the food came to me and was much less frenetic. The full board plus really is fantastic value for money if you do this. basically nobody eats or expected to eat anything outside meal times. I didnt have to carry snacks or pay for any other food or drink.
