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.
A sirloin roast of 8- to 12-lbs will take 16-20 minutes for rare, 20-22 for medium rare, 23-25 for medium, and 26-30 for well done. A boneless top round, by contrast, will take 28-30 minutes for rare, 30-33 for medium rare, 34-38 for medium, and 40-45 for well done.
