Has anyone here rented a car seat through Alamo? Was it clean and in decent condition?

I'm also open to recommendations other companies if you've had a good experience with them. Right now it appears Alamo would be the cheapest, and they guarantee availability with an airport reservation.

If I weren't going to be travelling alone with LO then I would just buy a Cosco Scenera, but I can't fathom juggling the stroller, diaper bag, suitcase, car seat, and a wandering toddler on my own
