I just cooked a full turkey dinner at VGC 2 nights ago, as a test run for future trips. I brought everything with me in a cooler, including a disposable aluminum roasting pan, spices, jarred gravy, potatoes, can of green beans, boxed stuffing, butter, and those pop up buttons that tell you when it's done.
The resort did not have meat thermometers, I asked, and there was no mashing tool, so I roasted the potatoes.
Once everything was in the oven we walked over to DTD for a bit, shopped, and as the villas are so close to DCA and DTD, we would run back to see how it was cooking, and then go back out.
I have to say it was one of my best roast turkey dinners. Not completely homemade, but close.
