I have been reading this post, but still have a couple of questions:
1. Is it sufficient with an ID like a bank card or drivers licence, or do you have to bring your passport at all times?
2. Is it illegal to bring 2 gals to your hotel room, or is it only illegal for WG?
3. What if there are two bros also? Is 2+2 illegal?
4. What are the consequences of being caught engaging in illegal activities (in general and worst case)?
