I don't think of August as a travel month. I get the impression the travel industry thinks the same: the articles give a few examples, and then skip ahead to September and autumn. TripAdvisor's Travelers' Choice Awards says that the best vacations in the world are:
New York City
These all look like expensive vacations. Back in 2012, the Globe and Mail had an article on how much is too much to spend on a yearly vacation? The article says that Canadian should allocate no more than 4 per cent of their after-tax income to yearly vacations.
According to American Express, the average vacation expense per person in the United States is $1,145 per person or $4,580 for a family of four. "In the States, financial experts suggest that the average family vacation costs between 5-10% of total income. If your family makes $40,000 per year then experts say your yearly family vacation budget should average between $2,000-$4000." That's double what the Canadian article recommended to Canadians.
It doesn't seem like there's an intersection between a trip to London and taking pictures of clouds as vacation activities.
