The family market is extremely lucrative so the liklihood of every hotel applying this rule is slim to none. Most resorts don't have this type of stringent policy so I think having a few that do actually makes things more inclusive for those with additional needs? A lot of people have disabilities/conditions that make noise intolerable which makes a lot of places inaccessible.
This is also a fantastic point.
One of DDs schoolfriends has huge problems tolerating loud noises. Shes a very quiet child also due to this, understandably. This kind of place would be great for her, where the more..traditional family places would likely be utter hell. A few places existing where screaming and such is not tolerated does make holidays in general more inclusive for people with all kinds of additional needs. Its not like its hard to find a loud, busy family place really, would even maybe be better if a few more places had stricter policies like this really, as usually the quiet type places are adults only, where a lot of children who cannot tolerate noise for various reasons exist and surely they would like to have a holiday too.
DD has issues with noises, especially very shrill piercing random ones. When we have holidayed in the past often her dad tends to keep her brother round the pool for a bit (he loves noise, and is..very energetic to put it mildly!) and I will take DD somewhere quieter, often a less busy beach for the day if she gets a bit overwhelmed. Fairly sure when DD is older and going away without us, she will be specifically looking for places such as this. If they are 'not allowed' because sme people with disabilities cant go there, then that is actively exclusing others with disabilities from ever going away really. There are plenty of places where a more excitable child is accomodated.
