Hotwire car rental and car seats

[sdjen]

hi everyone.

I am thinking about doing a Hotwire car rental for my upcoming trip. I will just need to get from close to the airport to Seaworld and back. I am wondering if I reserve on Hotwire if I can count on being able to get a booster seat when I pick up the car.

Has anyone ever done this? I am wondering if I do make the reservation, if I can call the car rental location directly and ask them to reserve one for me?

Thanks for any advice!
