I have a family of 3 (father, mother, child) currently staying in my condo. They said that their dad is coming over for a week to stay with them (they've booked my condo for a month). Although I appreciate them telling me, is it right for me to charge that extra guest even if he's staying for a week? They never mentioned anything before booking the place, just today right in the middle of their stay. I'm able to accomodate, so that's not a problem, but i was wondering if any of you have run into that situation. thanks!
