National Car Rental @Dolphin-Car seat ?

[chipmunkfan]

I will be renting a car through National at the Dolphin resort. I'm still debating about renting a car seat or bringing my own. Some people have posted in general, rental car seats are dirty and gross.
Has anyone rented a car seat from National at the Dolphin resort? What was the condition of the car seat?

I really find it hard to believe they would give you an outdated, nasty seat.

Looking for any reviews
