So reassuring to read all these responses.
I have 10yo ds1 who has Aspergers and ADD. He would very happily spend the entire fortnight watching pokemon videos on his iPad and playing minecraft, interspersed with play dates with school friends (he is quite social as long as he's in his comfort zone and is blessed with a good sized group of like minded friends, some quirky boys and some on the spectrum) and a bit of bouncing on the trampoline. He would be quite happy not to leave the house at all but does definitely crave the company of others his own age / interests.
However I also have two younger DC-similar to you OP, a 5yo who is NT and 2yo who is NT but in full on toddler mode-and juggling everyone's needs is hard. Both of the younger two are pretty sunny natured and sociable. Perhaps unsurprisingly, DS1 finds them very irritating on a good day, utterly unbearable the rest of the time, and will generally avoid them if he can.
So it's a struggle.
This holiday I have booked him on a holiday club thing with his best mate for two days, and the rest of the time we've done the best we can. I compromise on allowing fairly extensive use of the iPad when we're in, as long as we do go out and about once a day. He can cope fine with an outing as long as I'm clear about what we're doing and for how long, and specify what screen time will be allowed before and after going out. He is also much much happier if he has one of his mates around or to join in.
What I have realised this holiday though is that he really, really needs a daily break from the younger two to stay sane. Fortunately he is independent and high functioning enough that I can happily leave him at home for short periods (up to an hour and a half, say) so I can take the younger two to the park and leave him having chill out time at home.
