DVC Members have fully equipped kitchens, and most of us have breakfast in our room on a good part of our vacation. We like to start our day slowly with some tea, a bowl of cereal, just kind of hanging around watching Headline News on TV and reading the paper. Because we've got a kitchen with a table, a living room with a sofa, etc., it's not like we're sitting on the bed eating granola bars. We're using actual dishes and silverware.
We also have a washre and dryer in our villa, and I always grabbed a bottle of laundry detergent--in order to get the brand we like!
When we aren't staying DVC we still have a compelling reason--water!! Now it's not as bad--but when that swill they call water "Zephyr Hills" was the WDW water, YUCK!!! Dasani or Poland Springs for us. WDW sells water for a ridiculous price, and if you go in the summer when you'll go through 5-6 bottles a day each, well, that adds up to well over $50 a day on water for the three of us!
Also, DH likes Diet Pepsi, can't get it at WDW.
