We love, love, love the DxDDP...and we usually end up with 3 meals a day, sometimes 2.
We appreciate eating three good meals a day because we don't eat that way at home and it makes it a complete vacation for us.
Usually I try for an early breakfast, mid afternoon lunch and a late dinner.
We find most meals usually take us around an hour, give or take 15 minutes or so, unless we want them to me more leisurely. We've even had signatures not take much more than an hour.
It looks like you are eating dinner really early. I assume that is because your family calls it a night early? If not...
Using your chosen venues, I would probably plan like this...
Sat:
Narcoosees dinner 5 pm (this would be fine depending on what time you arrive and what plans for the day were...we love Narcoossees!)
Sun:
Crystal Palace breakfast 8:30 (earliest sitting)
Artist Point dinner 5:30 (assuming you're staying at MK all day, this would be fine but I might move it a little later unless you are planning to be back in MK for Wishes...then it's perfect!)
Mon:
CRT breakfast 8:55 (I wouldn't do Cindy's for breakfast but if I were going to, it would be the first sitting)
San Angel Inn lunch 12:30 (I would make this BOG at around between 2pm and 3pm, I'm also not a fan for lunch)
Chefs du France 5:30 (I would make this The Wave for around between 7pm and 8pm...we've never done the Wave for dinner)
Tues:
Akershus breakfast 8:15 (earliest sitting)
BoG lunch 11:15 (I would make this San Angel Inn around between 2pm - 3pm)
The Wave dinner 5:15 (I would make this Chefs de France around 7pm...which would put you out in enough time for Illuminations)
Weds:
Tusker House breakfast 8:20 (Earliest sitting)
Via Napoli's dinner 6:15 (I would move this a bit later because AK has a lot of small bite kinda things that can be purchased using your smack credits that are really good!)
Thurs:
O'Hana breakfast 8:30 (earliest sitting)
Garden Grille lunch 12:25 (I would move this one to around 2pm)
Coral Reef dinner 5:30 (I would move this one later around 7pm or 8pm)
Fri:
The Wave breakfast 8:00 (this seems perfect)
California Grille dinner 5:20 (compared to your breakfast time, this is fine depending on what your plans are for the day)
Sat:
Cape May Minnie's buffet breakfast 8:30 (this is perfect depending on your plans for the day or what time you leave)
We have done the DxDDP many times and love it. It's a lot of food and it's a lot of dining but we find we like it. It's settle down and regroup time. We did our first OOP trip in July (Report on the way) and found lines and ordering and finding clean tables etc...were all time consuming also. SO I really don't think we felt any more tied to time while eating. Our last DxDDP trip was two weeks over Christmas and New Years and I have finished most of my dining review with ADR times, arrival times, sitting times, and length of meal times for most of the venues. I have two adults a 17 year old boy and a 12 year old girl but we have been doing the DxDDP since they were both considered children (they are Disney Adults now). I will tell you that our July experimental OOP trip has led us to believe we'd rather DXDDP it in the future!
