IAH Car Rental Question

Hi All,

I’m flying into Houston in the next couple of months to go cruising. My plan is to rent a car so I can do a few touristy bits before heading down to Galveston. This will be my first time travelling long haul with my baby and I’m panicking about how to get to the car rental place as I’ve read various conflicting reviews online. Is the distance walkable from the terminals to the car rental place? If not I assume there will be a shuttle which is accessible with a pram?
