I agree it might not be the best idea to commit to multiple daily ADR's on a first trip. Figuring out new things and attacking the parks can take up a lot of time as new guests, let alone worrying about getting to multiple ADR's. However, people need to it. If they intend on eating a sit down lunch and a sit down dinner, then I'd say go deluxe.
I completely disagree about the 'too much food' part.
12:00PM - 1TS Lunch
7:45PM - 2TS Dinner
Seven hour spacing even on a sedentary day should lead to hunger and even from a dietary standpoint. Seven hours between meals isn't even healthy from a metabolic and nutritional standpoint, let alone on a physically active trip like Disney. Even with three courses, many of the signature offerings are smaller portioned and a soup/salad shouldn't have anyone struggling to finish their entree.
Not sure if you've been on your trip yet. But we have always done the deluxe dining, even our 1st trip. We did learn that first time, that we did NOT need to make reservations for every single meal, that really was a bit restrictive.
However, if you want to eat good
I would def suggest it! Now we plan 2 sit down meals per day. Depending on how it works out and how hungry we are, we will either snack, stop for quick service (sometimes we even share the QS Meals, so we'll have more for 2 credit dining) for that 3rd meal . Do what works for you, but I wouldn't worry about "wasting" time eating. With the awesome environment and theming, most of the restaurants really are a big part of the Disney experience, in my opinion. I would suggest the Deluxe to anyone - honestly, the food is so overpriced, we wouldn't go and not do that. I think it's a great value for what you are getting, and you get a lot! As far as it being "too much" food. It could be if you ate 3 sit down meals per day, with the app, main course and dessert...however, the regular dining plan is only 1 sit down, 1 quick and 1 snack
So that's not enough. It's an evil trick....haha, so you'll spring for deluxe. But it works, and if you do regular DD you'll be buying more food especially if your considering signature dining! When we go, using deluxe we do not spend a dime extra on food, we just leave the tip. Those are my thought...just my two cents. Have a wonderful trip!
