Me and my family stay at Hilton Resorts on all of our vacations around the world. Today the Hilton was having an event by the beach where they were doing face painting and giving out balloons for all kids, my kids waited in line like everyone else to get their face painted. When it was finally their turn the lady doing the face painting rudely told them you are not part of the event and asked them to leave because it is a private event!!! This event was on the pool deck below our room, we could see and hear everything from our room. The event was open and accessible to all with no signs or barricades (that we could see) what so ever indicating that this is a private event. My 3 and year 4 years when they heard the music and saw balloons/face painting they got very excited and wanted to do it too. Kids at this age don't understand what a private event means and honestly we are on vacation so if we can see celebrations and festivities from our room then it should be shared for all. we are extremely disappointed in the Hilton management for treating us this way, my kids were extremely sad all night. I spoke to management at the front desk but no one seemed to care or did anything about it.
