I was staying at a hotel for business last year when a couple with about 5 kids checked in on my floor. Two of the kids were about 4 or 5 years old and they ran up and down the hallway screaming at 10 pm. I got up and told the parents that I had to get up at 4:00 a.m. to go to work and asked them to keep there kids quiet. They acted like it was a totally unreasonable request. They told me that the kids had been cooped up in the car all day and needed to blow off some steam.
Most hotels nowdays have a gym. You should have told them to take them to the gym and put them on a treadmill for 10 minutes and make them run!
Examples like yours are reasons I try to avoid groups of people in general.
My parents would have never allowed me or my sister to act like that.
I would have called the front desk and raised hell with them until they stopped the disturbance or moved them or me.
