As summer turns to fall, not even cooler weather can dampen enthusiasm for Europe, which took six of the top 10 slots on the list. The Netherlands and Germany are particularly popular options for river cruisers wanting to visit the celebrated Christmas markets. Other travelers are focusing on warm-weather spots as the weather turns, such as South Africa, Mexico and Australia. In particular, South Africa continues to attract upscale explorers due to its wide array of adventure experiences. Increasingly, travelers are also discovering China for its combination of compelling history, rapid growth, improving infrastructure and increased luxury offerings.
