Thank you for the wealth of information y'all have provided.
I don't know if your son would like to be on the DxDP that's a lot of siting at restaurants waiting for food
How many nights are you staying?
We own a restaurant, so (un)fortunately hes more used to eating out than eating in.

Were staying a total of 8 nights.
We also definitely plan on utilizing child care for half of the dinners as we want him to be able to interact with other children, and not feel like he needs to sit.
You have a lot of fixed price restaurants on your list. In fact, at least half are fixed price
I would use the credits anyway but you don't need to feel pressured to use them if there's nothing he'd like to eat on the kids' menus.
Thanks for the scoop. Hes not really a kids meal kind of kid, so I was concerned about wasting his credits. I didnt know so many were prix fixe, thanks for the scoop!
Your Sunday plan of Boma, Chefs de France, and Victoria and Albert really has you running around a LOT. You will need to hoof it from either the Grand Floridian or Poly out to the Animal Kingdom Lodge for breakfast, which can be a real pain first thing in the morning if you are relying on Disney transportation.
For your dinner at Victoria and Albert's hire childcare. Either in room or one of the Children's Centers. There is no kids menu there, so your little one will be charged $125 for dinner. Better to pay for the child care center which will provide a kid centric dinner for the child and allow the adults some wonderful adult time together.
Thanks for the scoop on our Sunday plan being to ambitious. Its a non-park day as were sending the little one off on a pirate adventure, so I just picked a few places some friends had recommended. Were using child care for our dinner at VA as well. Thanks for the much appreciated info on Marrakesh. Some friends recommended it, but its been years since theyve gone. Do you have any alternate suggestions?
Not math related, but I just want to suggest that you pay careful attention to the spacing between your ADRs. You are planning 3 TS per day. Try keep at least 5-6 hours between them.
In terms of value, just a quick look and some mental math says you are probably coming out ahead on the DxDDp with these. Add in 2 snacks per person per day and you are doing even better. Is this what you would want as your TS line up if you were not considering the DxDDP (I mean if price was not a factor)?
We were planning on breakfast around 7:30, lunch around 1 and dinner around 7. That's similar to what we do at home. We also planned restaurants right at where we'll be park wise, so there shouldn't be too much travel.
Worse case scenario we'll just cancel some for the end of the trip if our plan seems to be too ambitious. Price isnt a factor and based on the fact we generally share 2 apps, 1 entrée and 1 dessert between the three of us, I wasnt sure if this plan was right for us. None of us drink soda either, just water (or booze, haha).
On your first stay you're using 5 of the 6 credits. Are you arriving really early in the morning (looks like Sat.) or will you be checking in the night before?
We get in on a Friday night at 6:15. Our plan for days is up early for breakfast at 7:30, parks from 9ish until 1, lunch then back to the hotel to play/swim/nap and head out for dinner around 6-7pm. Were there for 8 days total so Id say we have equal time in the parks and equal time for down time, or looking forward to our next meal.
So overall it seems as if the DxDP would be a good idea, but considering how we normally dine (an app or 2, 1 entree and *maybe* 1 dessert), I'm concerned it will be too much food. I'm also worried about quickly burning through our credits with the amount of signature restaurants we plan on visiting. We also don't drink soda, so I wondering if that would be lost on us.
I suppose I have time to think on it, as our 180 days isnt until June 3rd, or around there. ☺
Thanks so much everyone, I really appreciate the input!
