The old saying, "it isn't what you know, but who you know," is especially true when it comes to knowing which destination to visit next. Each November, the Deal Experts at Travelzoo Inc announce their list of wow destinations for the year ahead, predicting where travellers are likely to find the best bang for their buck. Last year, Travelzoo highlighted that European river cruises would present tremendous value in 2014. This prediction came true; Travelzoo saw a 40% increase in the number of European river cruise deals in its Top 20 list this year, compared with 2013. Deal Experts agree that the five wow destinations for 2015 are Brazil, Asia by cruise, Puerto Rico, Texas Hill Country (Austin & San Antonio) and Dubai.
