Plantation Bay is one of the very few hotels in the world that proactively and strictly defends our guests' right to peace and quiet (don't you wish airlines, airports, restaurants, and other public venues would do the same?)
No, frankly, I don't (and I speak as one who is extremely noise-intolerant). If I travel by rail I book the quiet coach, but I also take noise-cancelling earphones because I know full well others won't respect those rules and have no intention of sitting tutting, shooting daggers or having to tell someone else they need to shut up. I make my own provisions against noise, because if we all spent our lives being pissed with rule people we'd be spending an awful lot of time angry.
Babies cry. People want to talk and chatter, etc. We might - shock horror! - actually encounter some non-NT people.
Noisy I personally am not, but I wouldn't be particularly keen on the Headmaster Ritual from cabin crew, ground staff etc in the event that my kid has a tantrum, as tired, tetchy travelling kids are wont to do.
This resort is not a place for children, NT or otherwise, and it doesn't sound exactly a barrel of laughs for adults either. Even the ones like me who do appreciate a bit of peace and quiet. It should advertise as staid, silent adults only, as I can't imagine any children are very welcome. Being 'seen and not heard' is the condition of an exam room, not a relaxing holiday.
They've said what they want (and I don't for one moment believe 'special Mum' was a real guest anyway). Potential customers can go there or vote with their feet. The Manager's attitude would put a lot of people's backs up.
