While well-heeled travelers are still headed to Europe this summer, Australia and China are growing rapidly, according to new data from Virtuoso. Here's a look at the top luxury destinations for this summer. 
The Virtuoso Top 10
The most popular destinations for summer vacations based on future bookings:
1. United Kingdom
2. Italy
3. France
4. Canada
5. Spain
6. Germany
7. Netherlands
8. South Africa
9. Ireland
10. Greece
While Europe continues to dominate the list of favored destinations, the network's overall sales to Europe are slightly down by four percent when compared to the same timeframe in 2014. That said, the United Kingdom maintains its stronghold as the number one spot for travelers. Bookings for Spain are up four percent and Germany is seeing a seven percent increase, most likely driven by their relative value. The average daily rate (ADR) for Virtuoso's partner hotels in Spain comes in almost 35 percent lower than the European average of $761 per night, while Germany's hotel ADRs are about half the European average at $419 per night. With a 20 percent increase in bookings, Canada is the fastest growing of the Top 10 Destinations and Vancouver is the big winner, accounting for almost half of the network's air bookings.
The Virtuoso Hot 10
The countries that have seen the largest percentage of growth in year-over-year bookings:
1. Australia (+137%)
2. China (+101%)
3. Ecuador (+84%)
4. Iceland (+49%)
5. Greece (+41%)
6. Japan (+35%)
7. Turkey (+29%)
8. United Arab Emirates (+22%)
9. Canada (+20%)
10. Croatia (+18%)
Australia leads the chart with triple-digit growth, indicating that winter travel to Down Under is gaining in popularity. China trailed closely behind, largely thanks to Hong Kong which accounts for almost half of its air traffic. This year, Ecuador became the fastest growing destination – as well as the most popular – in South America. It is no surprise that summer is the time to visit Iceland, though the 49 percent jump shows that plenty of travelers are eager to explore it. And travel to Greece is back on the rise, with 58 percent of bookings occurring June through August as travelers head to their favorite isles: Santorini, Mykonos, Crete and Rhodes.
Data is sourced from Virtuoso's United States- and Canada-based travel agency members. The findings were announced during the group's annual Symposium taking place in Hong Kong this week.
