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.
How long and at what temperature should I cook a beef roast in the oven? Roasting is a great cooking method for a large, tender cut of beef  such as a rib or sirloin roast.Sirloin-tip, rump, rolled-rump, eye-of-round or top-round roasts will also benefit from this cooking method if they are graded prime or choice. 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.
