Should I list my friend's address or a hotel address on the TDAC form when entering Thailand?

When filling out the TDAC form for entry into Thailand, it's advisable to write the address where you will be staying. If it's at a friend's house, you can use that address without worry. Alternatively, if you prefer, you could write the address of any hotel in Bangkok; there is no requirement for a reservation to show. The consensus from community comments is that using a friend's address is acceptable. No immigration officer is likely to question this.
