I'm not the management at this hotel but was a very happy n satisfied guest. No, they don't charge extra guests. Just walk in, no problem.
I didn't have extra guest
But assuming the guest is humble polite and quiet they would not care.
Normally problems when breakfast is included in charge.
But this place is operated as international standard.
Not low cost pension/B&B
