This afternoon I received an email from Rocketmiles, offering an extra 500 miles on my next booking if I answered the five questions in their quiz correctly. I answered the five questions correctly and had a look at the hotel awards. UPDATE: This offer is not in conjunction with the 'earn 3-4000 miles on your first booking' offer. So for example, if you booked a room at the Hilton Garden Inn at LHR, you'd earn 1000 avios plus 500 bonus. Here's the email: "Barefoot in the Garden with a Bonus QUIZ ENDS APRIL 22 Get 500 fresh bonus Avios to begin the season. Take our quiz for your chance to use that art history course you took once upon a semester. We knew it would come in handy one day. Match each spring-inspired painting to the correct artist for a bouquet of 500 bonus Avios on your next booking. A perfect 5/5 score will take you to a winner’s page where you can claim your prize and get on your vacation faster!" Then there's a link to take you to the quiz. Looks like it's unique to each user - a long set of alphanumerical characters. Quiz answers: 1. Claude Monet 2. Gustav Klimt 3. Sir Lawrence Alma Tadema 4. Vincent Van Gogh 5. Sandro Botticelli
