@Megan *******
I know what you meant, but I believe it's not necessary in your case.
Same for me when I came to live here initially with extended family.
The immigration were not interested when I attempted to give them the address.
If it remains an issue per say maybe your friend just books a hotel for one night and you guys can go out in BKK for the evening?
Anyway enjoy catching up people you haven't seen in a while.
Don't forget the TM30. 🙂
