Best seat placement for RF & FF in 2012 Odyssey

[barnone]

I am trying to determine the best configuration for 1 FF Britax Marathon and 1 RF Marathon in our Odyssey. Right now (baby is still in Snugride), they are both outboard. But access to the 3rd row is tricky. Do I put them next to each other and take the passenger side seat out of the car for easier 3rd row access? Or keep them both outboard? I could put my older DD in the third row, but she still needs help buckling.

If they are next to each other, does the RF seat go in the middle for the baby? Or my 5 yo FF in the middle?

Any help is appreciated. TIA!!
