Had this happen once at a TPA property, but it wasn't just kids, it was flight crews. The driver called into the front desk and they directed me to take a cab, get a receipt and they would take the charge off the room. (Long enough ago that he called in on a walkie-talkie type device.) At check-in, I thanked the manager on duty and said something along the lines of that it was handled so well that I didn't mind giving up the Marriott Points. Sure enough, they even gave me the extra points.
This was several years ago. I've stayed at the property many times since then, and even feel guilty when I'm in the area and stay at a different property. For the price of a cheap cab ride and a very small number of points, the Westshore SHS bought tremendous goodwill.
