I get what you're saying, but as the parent of a special needs child, I ask you to consider that the child you perceive as misbehaving may actually be dysregulated due to a disability or special need you aren't aware of. They may be autistic, have adhd or anxiety, or another condition that may not be immediately visible to you. Royal Caribbean in particular is extremely autism friendly, so a lot of parents of autistic children choose to travel on RC. And while yes, some parents "don't parent", in the case of a special needs child, it can be extremely difficult to calm them or anticipate a trigger, especially in a new environment like a cruise ship. I'd also encourage you to look up "strategic ignoring" or "tactical ignoring", which is a recognized technic for eliminating bad behavior in children with or without special needs. Just because a parent isn't parenting their child the way you feel is appropriate doesn't mean they are not parenting in a way that a medical professional has advised them. And in response to your "if you can't parent your kids, don't take them out in public," I could just as easily say, "if you can't handle being around kids, you shouldn't cruise on a family friendly cruise line." There are cruise lines that cater to pretty much anyone, including those who don't want to deal with kids (ex. Virgin Voyages). It is your choice to choose a ship that caters to families with young children. Any family who is on that boat, who paid the same cruise fare you did (or likely more, given that accessible rooms and/or staterooms that hold more people tend to cost significantly more than two-person staterooms, as there are fewer of them on the ship) has the right to be there and enjoy their vacation, just as you do (and trust me, if a special needs child has a public meltdown, believe me that the parents likely are far more mortified and shaken by it than you are, even if they don't outwardly express it). And finally, I ask you to consider that families of children with disabilities and/or special needs, particularly autism, likely already feel stigmatized and isolated enough without reading comments like yours. And this should go without saying, but families of children with disabilities and special needs don't need to stay out of the public. They have every right to be there, just as you do.
