Last trip in 2011 my family felt I was a little in combat mode and DH wants a slower pace this time - so I need to make sure I don't turn him off (at his point he likes Disney but is not sure after this trip he wants to go again.) The goal is to keep is fun and relaxing as to not rock the boat away from The Mouse - the kids and I have an evil plan in the works and his is none the wiser.
With the above quote said, and the fact that you are on the DelDDP of 3 TS credits per night, you may want to be very considerate of how you space and use those credits to gaurd against the "Commando Diner" vacation. Imagine a day with three separate ADR's mixed in with park touring and how that would look and feel, then multiple that by 7 (days). So planning is important to pull that off. Not down to the minute OCD planning, but just good sense scheduling that does not self-conflict. Obviously, I do not know you, your family, or your situation, etc., but I would say:
I think the poster that suggested getting hoppers is onto something. Otherwise, your TS choices are limited to those offered at one park each day, or you have additional commuting involved to eat at resorts, creating more running around, which is counter to slower pace usually.
I know you said they like to eat 3-5 times a day. Remember on the plan you are on, you will get an app, entree, and desert. It is a lot to eat. We went to signatures and had two big meals a day(1 credit TS + 2 credit TS). We used snack credits to piece together light breakfasts, or get through lunch. This meant only two "appointments" to keep each day, which is condusive to a relaxed pace. If your husband is a foodie, he may enjoy quality over quanity. Do not want to take the kids to a bunch of really nice places? Go to Hoop-Dee-Doo Revue one night. Another way we accomplished this is by using a TS credit on check in day and check out day, spreading it around a little.
Lastly, there is a great 1 credit TS place at your resort in Boatwrights. Fewer things can be relaxing as a good TS meal right there at your resort.
