We have stayed in Hyatt many times before and find the service to be excellent and the rooms comfortable. However, this time there was a problem with using the pool. Families with children would completely takeover – jumping, diving, splashing, and screaming despite the signs clearly displayed and advising against it. The stuff would shrug their shoulders saying that they tell them but to no avail. We understand that it must be very difficult (and not advisable) to manage other peoples’ children. But you could manage the pool by introducing specific times for families only, line swimming or open to all. In other words, by managing the pool you manage its users – not the other way around!
