Thanks ellen, that's reassuring. The electronic passport thing sounds like a really good system. Sorry the coach ride problems haven't been resolved. 
We don't have all that many options really. Its basically between the local (what would have been catchment) school - where ds wants to go because all his classmates will be going there, or a school about 3 miles away that has a resource unit which does take children with ASD, but only if they also have more severe language/communication issues. Apparently the latter school has a reputation for being very good at supporting children with SENs anyway, even outside of the unit and particularly children with AS, but getting him to and from there would be a nightmare, he won't know a soul - so persuading him to go might be impossible - and of course he has his heart set on the local school (which is only half a mile up the road).
The local school is a bit of an unknown quantity, as it has changed a lot recently. It's become an academy and got rid of an awful head teacher, replacing her with one, I am told, is very good. I do know of a boy from our school, who also has AS, who went there the year before last and is doing well, as is ds1's friend's sister, who also has AS, so am hoping it might work for him. He really just wants to go where his best friend goes, but there's still a question mark over him going to Grammar at the moment, so I need to have a conversation with his mum, as if he is there's no point in including him as an extra factor in decision making. Of course I have to explain to ds that even if he goes to the same school as his best friend, he won't be in all the same classes - he's not going to take that well at all.
It all feels very big and scary at the moment and no matter what we do, I don't think ds is going to handle it very well. 
On a more positive note, he has had a bit of a breakthrough today. I decided to put Puss in Boots on pay-per-view for ds2 as a treat, seeing as he's poorly. Bearing in mind ds1's feature film/movie phobia, I suggested he might like to use my laptop in the kitchen while we watched it, but he surprised me by saying he would use it in the living room and then if he felt like it, he could try and watch some.
So that's what we did and after ten minutes, he put the laptop down and watched the film with us! [bugrin] [bugrin] [bugrin] He was visibly tense and obviously struggling a few times, but he sat through the whole film and said he'd enjoyed it! [bugrin] In the past, he wouldn't even agree to be in the kitchen with the door shut while we watched a film - so this is massive!
I am so proud of him for even trying, let alone getting through the whole movie. It was totally out of the blue as well, I didn't even ask if he wanted to watch it, it was his own suggestion. [busmile]
I know it seems an odd thing to be pleased about - that your (almost) ten year old ds has just watched a kids film - but I know you guys will understand why I am so [bugrin] about it!
