Can we appeal for transport to specialist school if we've said we'll organise it?

D14, autistic, SPD has been given a placement at an independent specialist. Nearest mainstream said they could still meet need (though they have to say that, right?) so we've had to agree to transport my daughter. Daughter lives with dad (my ex) and he now says he can't transport every day (he's a lecturer and his work can't put all his lectures during her school hours). I'm 90 minutes away and disabled. The EHCP is still in draft as moved from one LA to current after draft received and EHCP is vague and missing huge amount of necessary detail. Annual Review to be held 6 weeks into first term to transfer ECHP into new LA's format etc. Main issue for my daughter is environment so mainstream could meet academic need but she'd not be able to attend as she needs a small, quite setting. Is there any point trying to appeal this? Do I wait until the Annual Review and hope the EHCP is more detailed and therefore it's easier to prove that the mainstream can't meet need? Very frustrated that I've worked for a year to get her an EHCP and a suitable placement for her to risk losing it!
