Car seats available in WDW taxis/vans?

[Carrie Gruber]

We'll be traveling with an 8 yr old, a 6 yr old and a 14-month old this October. Older kids won't need a car seat, but for the baby I'm curious about the availability of car seats in the taxis/vans that are staged at the resort. We'll be at AoA, I know we have to request a car seat when we tell the CM that we need a taxi/van but does anyone know what types of seats they use? Are they old, outdated ones or relatively new? As far as germs, I'll wipe it down with disinfecting wipes. I'm more concerned about the quality of the seat. I'm not comfortable with having him sit on our laps...on a bus it's understandable, but in a regular car/van I'm not going to feel completely safe unless he's buckled in (and the seat is installed by me or my husband) TIA!
