Just wanted to say I use to work for a 5 star hotel resort in their activities department. This was a few years ago (8) but back then the hotel babysitters were staff (generally either from activities department or housekeeping (mums)). We put our names down saying we were willing to babysit so don't necessarily assume it is from a babysitting/nanny company.

At the time it was good money coz we got cash in hand from the parents. The hotel didn't get anything it was just a service they arranged.
