What should I show immigration in Thailand if asked where I will stay during my visit?

When arriving in Thailand, it's quite rare for immigration officials to ask where you will be staying. If they do inquire, you can simply provide the address of the place where you'll be staying, such as your aunt's residence, rather than needing to show a rental contract or proof of a hotel booking. While some suggest booking a hotel for at least one night to be safe, many travelers report that they were not asked about their accommodation during their entry.
