Depending on where you look for guidance on the 'Top Places to Travel in 2020' there are numerous opinions.
Conde Nast has Matera - Italy, Valle de Guadalupe - Mexico's Wine country, New Orleans - US, Tasmania - Australia and Transylvania - Romania as it's top 5 hitters
British Airways on the other hand has New York - US, Orlando - US, Las Vegas - US, Dubai - UAE and Barbados as its prime destinations. It goes without saying that travel and flight companies are likely to be skewed in their opinions.
Of course the type of holiday or trip you want to take whether it's an epic adventure or your annual family holiday will also have a bearing along with budget, previous travel and your personal style.
From what I've seen so far for 2020 the top destinations for my clients are:
*Peru especially Machu Picchu*
*New York/Las Vegas*
