Would it be a good idea to split a hotel bill evenly, even if one of the occupants is a kid?
Wait, why would you split the bill with a kid?
Why shouldn't I?
It's wrong to split a bill with kids because they don't have jobs. You should've figured how you were going to finance this trip beforehand and discussed it with their parents if you were unprepared to pay. It's not OK to invite kids and then demand they pay their way afterwards.
Do I really have to pay for this kid simply because he's a kid? I seriously doubt that.
If you invited the kid and didn't ask their parents for the money, then yes. The kid themselves can't be held responsible in this situation. You shouldn't expect a kid to pay for things like that.
