We're seasoned Disney travelers with 51 trips so far and never ever on a dining plan....
We're frugal, maybe cheap even...I've always gone with the pretension that ....
Breakfast per adult:: 8.00
Lunch.... We do pool picnic with sandwich fixings we picked up in route at Publix...
Dinner:: we're not foodies and aren't into the so called signature restaurants but... 15.00 per adult at resort food courts suits us fine...
So, bottom line per adult, let's say 35-40.00 counting a few snacks at the parks
That said, most Disney meals are huge, easily shared ( which we often do )... we often splurge maybe 2 times per 7 day visit with a meal at Yachtsman Steakhouse and Raglan Road... Those are food specific...
As I said, we're at WDW for the parks and relaxation... we prefer homemade food over restaurant food hence our sandwich making stuff from the grocery store... we also purchase alcohol , beer wine and soda at the store and never buy on Disney property...we break around noon or before each day and spend 3-5 hours at the resort pool or room....and consume our goodies so our budget is very small compared to others that go full all out on Disney dining..
