I don't think shark was meaning that disadvantaged kids can't access it another time, just that it so happens that this week has been the only good weather out of a pretty piss poor summer so far, so naturally there is going to be a hell of a lot more people wanting to use the park, and that for a poor family on a nice day, its naturally the kind of place they'd gravitate towards as its presumably free, and she would feel a little mean throwing kids out on one of the only fine days of the year. thats all that was meant.
i think this thread just goes to show that as a previous poster said, parents of children with SN do not have a hive mind, and what is ok for one family with SN is not necessarily right for another, nor to two people think the same way. from my own perspective, it just seems that setting a session in an un-manned place like a splash park, isn't going to work very well. lots will not have seen the signs, lots will maybe misinterpret the sign as there being things on for SN, but not that they should leave. and of course, some may just not care.
