I have been travelling for the last 4-odd years. Rarely stay in a place more than a week. Often for less time. I don't know the names of half of the hotels/hostels/etc I stayed at. How do I fill out this part of the application? Has anyone done this? My "official" address at this time has been my parents' house.

No interest in lying. No way I can answer this question fully. Am I out of luck?
