Well, that may be for Disney's pocketbook, anyway.
We have taken at least a dozen trips as a couple only to WDW. I will continue to do it as a couple only thing in the future, too. With that said this is what we do for a family vacation there:
The one thing we have done with kids including grandkids to help out with the fighting factor, etc. is to set-up a system where everyone has a say with the trip. This includes before you get there and during your trip. We have even gone as far as signing a contract with one another for vacation. If it's breached, there are consequences. It's my business degree getting the best of me, here. In fairness, as the parents, we need to schedule down time on vacation for naps, rests, and even taking a break from the parks mid-way through the trip. Do not go FULL BLAST with Disney day in, day out. It just doesn't work.
I think a great way to help out in the parks is to give everyone a camera. It pacifies all for the moment; so, you can at least have some restful moments there. For the wee ones, they will need toys, etc. to bring to the parks. Bring snacks or buy them there. If a child is hungry, it can get them to be crabby real fast, etc. You need to take turns with choices of what to do, where to eat, etc. and this includes adult activites. We even give an allowance for spending everyday for souvenirs and the like; so, everyone can do what they want with their spending money each day. It's well understood there are no extras with the spending money; once you spend it; that's it. We simply try to take the argument out of vacation. It takes alot of time and effort to do it this way, but the results have proven itself that this method works for us, year after year.
We had a bad moment with our grandkids once in a 2000 trip; so, grandpa stayed behind with one grandson while grandma went with the other two for the day. This seemed to cure the problem; because, those type of actions where not repeated by anyone for the rest of the trip. It seems noone wants to be out of the loop; they are afraid they are missing out. It's a great motivator to keep peace. We took turns with car seating and with who sat with who at the shows and rides, etc. We both spent individual, quality time with each child. We spent time talking and listening to each grandchild. We even did this at the resort, not just the parks. Personal attention is important. Compliments don't hurt, either. If we saw an act of kindness towards each other, we made a big deal about it.
Disney is a tempting place to be selfish. I think you need to establish ground rules to make a vacation great no matter what the destination. It still is not 100% perfect, but I'll take 90% with our family and I'll consider it a great vacation. Good luck to all on future trips with your loved ones on vacation.
