We are at WDW right now and have been doing a combination of cooking and eating out. It has worked great so far.
Last year we did the
ddp for 20 nights and it was way too much food!! We vowed never to do that again. It also helped with the decision that our ds just turned 10 and we would have to pay adult pricing if we were on the dining plan.
We spent our first week at Vero beach so I stocked up and precooked a lot of meat for the WDW portion of out trip. I bought hamburger meat and a bag of chicken, cooked it all and then separated it into small portions for our lunches/dinners. So far we have eaten spaghetti, burritos, BBQ chicken sandwiches and shredded chicken quesadillas. It has been easy and does not take a lot of time from our vacation.
We are very relaxed when we tour the park and usually hit the parks first thing in the morning, come back to the room to swim and rest during the afternoon and then head back out after dinner. This way we are usually able to eat at least lunch or dinner in the room. Then we usually get dessert when we are out in the parks in the evening. We also eat a quick and easy breakfast ( cereal, bagels etc.) before heading out to the parks.
I agree that eating out for 22 days is way to much after our experience last year. It has been wonderful to eat when we want and not rushing to another reservation or spending all of our time eating. We were very lucky last year that we got to try so many different restaurants, but at least for this year, we have been content to enjoy our favorite meals out and then just play it by ear for re rest.
