Travel, is one of the 4 starting points. It is a wide-range topic for doing the research if compares to some topics on the list. First, I have done a mindmap on topic "Travel", have found some information from internet that may relevant to it. Then, pictures/photographs are really helpful to understand "Travel". Also, A few shot videos are useful to explore the purposes of travel to understand how do people usually travel; what transport do they use, and where do they prefer to live.
The mind map contains some ideas on 'Tourist accommodations' and 'purposes'. Also 'Traffic' are important to understand what transport tools people usually choose. 'Time managment' to discover how a traveller allocate time in a day.
What types accommodation would be chosen by travelers? It depends on consumer groups and their consumption opinions. Most travelers prefer to live in hotels while they traveling rather than other types of accommodation. Hotels normally provide a quieter, safer and more private space for lodgers. Also contains better service, luxury decoration and convenient place.
Hostels and cottages also good choices for some travelers due to cheaper cost. Homestay is usually for people who has a long time stay demand. Campsite is usually based on remote regions. Also B&B (bed and breakfast) is popular in worldwide. Travelers cost a low price for a short period overnight stay, include a breakfast.
Nowadays, most young people prefer to reserve accommodation on mainstream websites, such as Booking, Airbnb, also Ctrip is quite popular in China. Some people prefer travel retail stores or get information from magazine, newspaper.
