Since this site suggests you book your Walt Disney World trip at least 180 days in advance of your arrival date, and the Disney website likely wonât allow that for 2016 dates until summer 2015 the earliest, knowing that there are ways to book out to 500 days ahead is really helpful !
Roast the turkey: The rule of thumb for cooking a turkey is 13 minutes per pound. So our 16-pound turkey was estimated to cook in about 3 1/2 hours. However, some factors like brining the bird, cooking with an empty (un-stuffed) cavity, and leaving the legs un-trussed will contribute to much faster cooking.
Tent the bird with foil. Roast the turkey for 2 hours. Remove the foil and baste with the remaining butter. Increase oven temperature to 425 degrees F and continue to roast until an instant read thermometer registers 165 degrees F in the thigh of the bird, about 45 minutes more.
