If you have your heart set on a certain resort during peak season go ahead and book as soon as possible! One other thing to keep in mind when booking a Walt Disney Vacation is if there is a special such as a room discount or free dining during your travel dates, it WILL NOT be automatically applied to your reservation.
Letting the roast rest for 10-15 minutes, pulls the juices back into the roast and results in juicy tender meat. Use a nice long craving knife to slice up the roast. There are many different cuts of beef and the top sirloin roast is one of my favourites.
In comparison, pork sirloin roasts, which have more fat than tenderloin and sometimes come with the bone-in, can take 1 hour and 35 minutes to cook in a 375 F oven. When cooked from frozen, they can take upwards of 2 hours and 15 minutes at the same oven temperature.
