DH doing the marathon, entertaining 2 autistic children???

[cheekymonk]

Hello all. My problem is as stated. DS is 12 and has ASD. I had some time just him and Intoday and we did IWP which he loved. Tomorrow however I will also have my DD who is 6 and has PDA. She and DS argue constantly and she is prone to running off. Am really not sure where to take them? I also want to cheer DH on but DS especially hates crowds so could be interesting?! I have mentioned to DH that of it gets that bad I will just catch train home (have come to London for weekend, live in Midlands)...
