Wikitravel:Other ways of seeing travel
The geographical hierarchy is one way to think about and organize travel articles - breaking down big areas on Earth's spherical surface into smaller and smaller areas until you get to areas too small to be worth writing an article about. But it's just one of many ways of thinking about travel articles, and to form meta-articles that group other articles together. Some other ways are listed below; there are probably more.
see also: List of itineraries
An itinerary views a group of destinations according to a temporal (time) division rather than a spatial one. For example, Summer in Europe or One month in Vietnam could list some cities and countries to visit during that amount of time, with recommended durations of stay. Weekend from New York might list multiple itineraries in Long Island, Connecticut, or other destinations.

Not all travellers are looking for general adventure and art museums. It also makes sense to think about travel issues - Disabled travellers, First aid kit for travellers, Gay and lesbian travel, Honeymoons, Travelling with children, or travel activities - golf, scuba diving, etc. Some information on these issues may go into geographical descriptions, but other more general info might be valuable in its own article.
